Question

If tan x°= z/10 and cos x°=10/y, what is the value of sin x°?

Answer 1

use the identity
tan x = sin x / cos x

so sin x = cos x * tan x
plug in z/10 and 10/y and simplify

Answer 2

ok im clueless, how could that even happen?

Answer 3

sin x = z / 10 * 10/y
the 10's cancel out
so sin x = z / y

Answer 4

another way to do this is to draw a right angled triangle
