PLEASE HELPP PRE CAL!!

Given..

Tan x = 3/4; sin (pi/2 - x)

What is sinx??

(I know its 3/5 but can someone show me how?!)

Step-by-step explanation:

tan x = 3/4

Tangent is opposite over adjacent, so draw a right triangle with angle x where the opposite side is 3 and the adjacent side is 4.

Use Pythagorean theorem to find the hypotenuse:

c² = 3² + 4²

c² = 25

c = 5

Sine is opposite over hypotenuse, so:

sin x = 3/5

the answer is c)8
