Question

Can anybody please help me get the answer or help me understand how to do this

Answer 1

51.3

Explanation:

This is a right triangle (because of the 90° angle). For any right triangle, you can use the following:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

You can remember this as SOH-CAH-TOA.

We want to find the angle y. We know that the opposite side is 10 and the adjacent side is 8. So we can use tangent:

tan y = 10 / 8

y ≈ 51.3°
