Question

XYZ is a right triangle. If XY = 4, what is YZ?

Answer 1

We are given

angle(Z)=30

Let's assume angle (Z) as reference angle

so, opposite=XY=4

adjacent=YZ

so, we can use tan formula

$tan(Z)=\frac{XY}{YZ}$

now, we can plug values

$tan(30)=\frac{4}{YZ}$

$YZ=\frac{4}{tan(30)}$

$YZ=4\sqrt{3}$...............Answer

Answer 2

The Answer is D. 16. 
XZ = 8/sin 30
