#

first off, you can determine the missing angles. that gives you more options later on.

#

i mean... if the problem is realistic, then its not right. no building in the world is this high

#

give me a minute

#

ok now i got 324.88

#

meters

#

lets call the base of the tower x

tan(63.3) = 100/x --> x=100/tan(63.3)

tan(81.2)=height/x=height/(100/tan(63.3))=height*tan(63.3)/100
--> height=100tan(81.2)/tan(63.3)

#

thats about 324.88

324.88

#

the solution i presented is correct as far as im concerned

I hope its readable....0.o

#

@steep vector red is Q and blue is working....

#

the answer is approx... (I had rounded the base)

#

well i guess you should start getting a grip on how sin, cos and tan work, because we cannot meet with your teacher.

#

that just stands for
soh: sin=opposite/hypotenuse
cah: cos=adjacent/hypotenuse
toa: tan=opposite/adjacent

#

?

#

oh

#

ok

polar palm Mar 7, 2024, 1:56 AM

#

i mean the stuff i presented was sin, cos, tan laws instead of ratios

toxic imp Mar 7, 2024, 1:56 AM

#

so you were supposed to use the trig RATIOS

polar palm Mar 7, 2024, 1:57 AM

#

toxic imp so you were supposed to use the trig RATIOS

but why tho, this is more complicated lol

#

soh, cah and toa literally stand for the trig laws

toxic imp Mar 7, 2024, 1:57 AM

#

polar palm but why tho, this is more complicated lol

what the trig ratios?

polar palm Mar 7, 2024, 1:57 AM

#

in this case yes

#

you told us to use sin, cos and tan (soh, cah, toa) and we did @steep vector

toxic imp Mar 7, 2024, 1:59 AM

#

💀 wait

#

@steep vector

#

are you in 10th grade math

#

or 11th grade

#

ohhh

#

cuz if you were in 11th

#

yeah wait

#

I could've just used trig ratios 💀

#

cuz they right triangles

#

ok

polar palm Mar 7, 2024, 2:00 AM

#

??? why would you learn trig ratios before learning trig laws?
where are you from?

#

oh alrighty

polar palm Mar 7, 2024, 2:11 AM

#

polar palm lets call the base of the tower x tan(63.3) = 100/x --> x=100/tan(63.3) tan(81...

this

#

this does not use sine law

#

@steep vector i found a video that might help you understanding whats going on

Maths Tutorial: Trigonometry SOH CAH TOA (trigonometric ratios)

SOH CAH TOA is used to remember the trigonometry ratios; sine = opposite over hypotenuse, cosine = adjacent over hypotenuse, tangent = opposite over adjacent. This helps you work out unknown side lengths or unknown angles in a right-angled triangle.
This video is a tutorial on how to apply this rule.

from where I am from

#

that is exactly what we o

#

do

@steep vector If this is a practice worksheet or something, I do not think you have to worry... Both methods are right and during exams, regardless of which rule you use, as long as the answer is correct and the formula is legit, you should be getting the marks. Yes, soh cah toa maybe longer but if you understand this method and are comfortable with using it, it shouldn't be a problem regardless of whichever grade you are in.

#

@steep vector also just curious, wuts a 10th pre cal? o_0
