So you have an angle...a side adjacent to that angle...and you want the side opposite that angle..

What trigonometric function uses opposite and adjacent?

anonymous · Answer

Uh...Sin Cos Tan???

johnweldon1993 · Answer

Hint* Remember SOH CAH TOA

it helps remember the trig functions

S     sin =
O   opposite
H   hypotenuse

C     cos =
A    adjacent
H    hypotenuse

T    tan =
O    opposite
A    adjacent

So which one is it?

I'm not sure, to be honest. I'm really bad at math.

@johnweldon1993   Uhm, Are you done helping or??

hoblos · Answer

tan = opposite/adjacent 
so tan65 = h/50

h=?

anonymous · Answer

Uhm...I don't know how to find that answer.

hoblos · Answer

you have    tan65 = h/50
can you find h from that ?

anonymous · Answer

I don't know how.

hoblos · Answer

multiply both sides by 50
what do you get ?

anonymous · Answer

Oh! 3250, 2500. Sorry for my slowness, I'm lagging and working on biology.
