for this we use pythag

#

given the two sides

#

he have the hyp (26) and the b side (25)

#

$given~c^2~=a^2~+~b^2$

Mr. Macro

#

we can solve for the square of side a by rearranging the formula

#

$a^2~=c^2~-~a^2$

dont forget to squreroot the answer

@finite brook its a bit blury

tulip basin Nov 8, 2023, 7:18 AM

#

use pythagoras- a^2- (a^2/4)= (10.4)^2

#

in the next one with a lot of triangles. You can see that the triangles fulfill pythagorathas with sides 3,4,5 and so those angles are 90. Now angle D is 90 so you again apply pythagoras in ADB and use sides a, 4, 8(5+3). Pt E divides AB in half since the middle triangle is isoceles, so another pythagoras with sides 5,a/2 and x

Last one with octagon- 2x+a = 8 and 2x^2= a^2. Sorry I don't know how to write properly

finite brook Nov 8, 2023, 7:31 AM

#

tulip basin use pythagoras- a^2- (a^2/4)= (10.4)^2

could u explain what pythagoras is?

#

and pythagorathas

#

how would i know if the sides fulfil it??

@finite brook this is the formula

#

c is the hypotenuse

#

a and b are the other sides

tulip basin Nov 8, 2023, 7:46 AM

#

this is a good video+ only works in right triangle. Right triangle always fulfills this condition. You see a right triangle, it is pythagoras time.

could u help me study for a chapter test? @tulip basin

#

#

these are the concepts and stuff but i dont understand anything

#

tulip basin Nov 9, 2023, 12:54 AM

#

I can teach you the concepts and help with doubts but you have to practice, if that's cool with you then sure @finite brook

finite brook Nov 9, 2023, 1:29 AM

tulip basin I can teach you the concepts and help with doubts but you have to practice, if ...

hii r u available rn?

@tulip basin

tulip basin Nov 9, 2023, 6:21 AM

#

Sure

#

@finite brook

finite brook Nov 9, 2023, 6:22 AM

#

hi!

tulip basin Nov 9, 2023, 6:22 AM

#

hello

#

so do I tell you here or is there some other place for this

finite brook Nov 9, 2023, 6:23 AM

#

here if ur ok w it

tulip basin Nov 9, 2023, 6:23 AM

#

I am ok with it

finite brook Nov 9, 2023, 6:23 AM

#

okk

tulip basin Nov 9, 2023, 6:24 AM

#

first is square and square root. Do you understand them or should I start from zero

#

@finite brook

#

hello? @finite brook

finite brook Nov 9, 2023, 6:30 AM

#

i understand it

#

sorry my phone was charging

#

i struggle with word problems though i just dont understand them

tulip basin Nov 9, 2023, 6:30 AM

#

Can you point out one of them for me from the pages you sent

finite brook Nov 9, 2023, 6:32 AM

#

#

like for example this

#

i wouldnt know how to make an equation based off the sentence

tulip basin Nov 9, 2023, 6:32 AM

#

Okay 1 second

#

okay so look, you know wht is horizon

#

it is how far you can look

finite brook Nov 9, 2023, 6:33 AM

#

mhm

tulip basin Nov 9, 2023, 6:34 AM

#

now the question is saying that this distance or your ability to see depends upon the height of the place you are standing

#

like if you go a higher building you can see far, if you ride a plane you can see farther

#

get that?

finite brook Nov 9, 2023, 6:34 AM

#

ohhh yes

tulip basin Nov 9, 2023, 6:35 AM

#

now he named this ability to see as d which is

#

3h/2^1/2

#

so here you just put h and find d. The question is basically about your understanding of horizon then maths itself. If you can figure out that when he was saying horizon he meant the ability to see then you just have to place h

finite brook Nov 9, 2023, 6:36 AM

#

yes

tulip basin Nov 9, 2023, 6:36 AM

#

The equation is already given here, you don't have to form anything

finite brook Nov 9, 2023, 6:36 AM

#

but how do i know what h is?

#

there are 2 variables

#

oh wait nvm

#

oops

tulip basin Nov 9, 2023, 6:36 AM

#

H is height

#

haha

finite brook Nov 9, 2023, 6:36 AM

#

😭

#

but how would i solve this?

tulip basin Nov 9, 2023, 6:36 AM

#

so you need help solving square roots?

finite brook Nov 9, 2023, 6:36 AM

#

like multiply 3 and 2 then make it 6h?

#

yea 😭😭😭

tulip basin Nov 9, 2023, 6:37 AM

#

so what is h in the question

#

the value of h in the question, what do you think that is

finite brook Nov 9, 2023, 6:37 AM

#

52

#

omg wait

#

no

#

huh i dont get it

tulip basin Nov 9, 2023, 6:38 AM

#

the h is what you have to find

finite brook Nov 9, 2023, 6:38 AM

#

do i have to divide by 2?

tulip basin Nov 9, 2023, 6:38 AM

#

that is the height of the tower

#

tall means height, you get that right?

finite brook Nov 9, 2023, 6:39 AM

#

yes

tulip basin Nov 9, 2023, 6:39 AM

#

so h is height okay and the question is asking for tallness so do you understand what the question is asking now?

#

if you don't understand don't worry

finite brook Nov 9, 2023, 6:40 AM

#

uhhh

#

😭

tulip basin Nov 9, 2023, 6:40 AM

#

I will start fro beginning but you have to tell me

#

see the first line is the distance to horizon is found using formula. What is distance to horizon here

#

what do you think it is I mean, in english

finite brook Nov 9, 2023, 6:41 AM

#

?????

tulip basin Nov 9, 2023, 6:42 AM

#

you have to speak more than that. I don't understand what you don't understand when you give that.

#

do you not understand what distance to horizon means in english or what I am asking here?

finite brook Nov 9, 2023, 6:42 AM

#

i dont know what ur asking

#

😭

#

i dont know how to solve it

tulip basin Nov 9, 2023, 6:43 AM

#

and I am teaching you, but you have to answer clearly okay and stop and tell me when you don't understand.

finite brook Nov 9, 2023, 6:44 AM

#

okok

tulip basin Nov 9, 2023, 6:45 AM

#

Horizon means where the earth meets sky

#

you understand that?

finite brook Nov 9, 2023, 6:45 AM

#

yes

tulip basin Nov 9, 2023, 6:45 AM

#

now in the first line of question

#

it says distance to horizon

#

that means your ability to see

finite brook Nov 9, 2023, 6:45 AM

#

wait

tulip basin Nov 9, 2023, 6:45 AM

#

as in if the distance is 10 m, you can only see 10 m

finite brook Nov 9, 2023, 6:45 AM

#

isnt horizon the distance from sky to ground?

tulip basin Nov 9, 2023, 6:46 AM

#

no

#

when you stand on your roof

#

and look far away

#

you see sky meeting earth right

finite brook Nov 9, 2023, 6:46 AM

#

ohhh so if i was at the bottom of a hill and i looked up then i would only be able to see 10m?

tulip basin Nov 9, 2023, 6:46 AM

#

better assume there's a wall in front of you that is horizon. So if the distance to horizon is 10 m then you can only see 10 m

#

right

finite brook Nov 9, 2023, 6:46 AM

#

yes

tulip basin Nov 9, 2023, 6:46 AM

#

this is easier

#

so distance to horizons means how far the wall blocking your vision is. If the wall is 10 m away then you can you only see 10 m, beyond it the wall will block your sight so you can't see. Do you understand this?

finite brook Nov 9, 2023, 6:47 AM

#

yes

tulip basin Nov 9, 2023, 6:48 AM

#

now check the formula for distance to horizon in the question.

#

it depends on h. What do you think this h is

finite brook Nov 9, 2023, 6:48 AM

#

the distance from where i am standing to the wall

tulip basin Nov 9, 2023, 6:49 AM

#

that is distance to horizon. d. read the first line of question again

finite brook Nov 9, 2023, 6:50 AM

#

the height above sea level? like how much tall i can see

tulip basin Nov 9, 2023, 6:50 AM

#

what is your height above ground

#

what do you think this expression means

#

do you not understand?

finite brook Nov 9, 2023, 6:55 AM

#

but how can i know how my height above ground is?

tulip basin Nov 9, 2023, 6:56 AM

#

do you not know your own height?

#

you can measure it with an inch tape

#

now the h in the question, it is the same thing. Ignore the sea level thing, every height is measured above sea level. It means nothing more than height measure with any instrument

#

so you understand d and h now right

#

?
