AB and BC are perpendicular lines

[nimble portal]

just need some help understanding it 🙂

@naive merlin

[torn yacht]

Any 2 perpendicular lines have an angle of 90° in between

[naive merlin]

what was your initial guess again?

[nimble portal]

it be a 90 degree angle and subtract 25 from that

[naive merlin]

you are close enough

okay so

[nimble portal]

really?

[naive merlin]

how many angles do you see?

[nimble portal]

2

a acute and a right

[naive merlin]

or a better question, can you break the 90 degree angle into its components?

like 90=a+b+c?

or whatever possible

[nimble portal]

dont quite follow haha

[naive merlin]

lemme send a ss

[nimble portal]

okok thank you

what is throwing me off though is if you look the bottom line is on a tad slant which made me double guess it a right angle

[naive merlin]

can you find the black angle using this?

[nimble portal]

its a 360 degree one right?

so youd sub all of the numbers from 360

[naive merlin]

nope :p

the black angle is equivalent of the sum of all the orange angles instead

[nimble portal]

haha they gave this video out but it didnt cover this part of the topic 😦

jeez this is alot more confusing than i thought

[naive merlin]

here, you can say black angle = 65+25+35

[nimble portal]

right

[naive merlin]

in your case we have

[nimble portal]

so its not sub from the right angle its add is that what u mean?

[naive merlin]

in this case, you have angle ABC = x+25+x

do you agree?

[nimble portal]

yhyh

[naive merlin]

what is the given value of ABC?

[nimble portal]

115?

[naive merlin]

hint: what is the angle formed by perpendicular lines?

[nimble portal]

uhhh not sure

[naive merlin]

perpendiculars always make 90 degree angle

[nimble portal]

right

ohhh so is there 2 90 degrees?

cuz AB and BC are perpen

[naive merlin]

if two lines are perpendicular to each other, regardless of how you draw them, the angle between them will stay 90 degree

so in your case

https://cdn.discordapp.com/attachments/1104039984610156585/1104039984891179120/image.png

angle ABC = 90 degree

but you also know that ABC = x+25+x

which means

90 = x+25+x

can you solve this equation?

[nimble portal]

27?

am i adding the 25 and the two x

[naive merlin]

27 is probably wrong

but yeah you are doing it right

[nimble portal]

yh 27 was wrong

[naive merlin]

,calc 75/2

[echo cape]

Result:

37.5

[naive merlin]

it should be this much

https://youtu.be/H-de6Tkxej8

also check this out and a couple other vids on their channel to understand how angles work

[nimble portal]

came out as wrong 😦

[naive merlin]

37.5 is wrong?

[nimble portal]

ill take a look at that later on cuz could be helpful for me to recap

yes it was wrong

[naive merlin]

,calc 2*37.5+25

[echo cape]

Result:

100

[naive merlin]

my bad

,calc 65/2

[echo cape]

Result:

32.5

[naive merlin]

it will be this much

[nimble portal]

yhyh that was right

[naive merlin]

2x+25 = 90
2x = 65
x = 65/2 = 32.5

[nimble portal]

still confusing how you get that so i will have to look at videos on perpen angles

ohhh

i get it now

2x+25 = 90
2x = 65
x = 65/2 = 32.5

this makes sense

so basically i was only getting the answer for one X

not two

tysm for helping
