Question

Which equation can we use to find the length of the side labeled x?
What is the value of x?

Answer 1

D. sin 30° = 5/x

Explanation:

recall that for a right triange, considering one of the acute angles θ

sin θ = length of opposite side / length of hypotenuse

from the picture, we can see that

θ = 30°, length of opposite site = 5 and length of hypotenuse = x

substituting this into the above equation

sin 30° = 5/x

Answer 2

option d

d ---- sin30 =5/x
