Does anybody know the answer to this ?

Problem 1

Explanation:

This is the leg furthest from angle X. Side XY is the adjacent side while XZ is the hypotenuse.

Problem 2

Explanation:

The tangent ratio is the opposite over adjacent. With angle X as the reference angle, we will then have ZY = 18 as the opposite side and XY = 24 as the adjacent, so,

tan(angle) = opposite/adjacent

tan(X) = ZY/XY

tan(X) = 18/24

tan(X) = (3*6)/(4*6)

tan(X) = 3/4
