HELLP it’s math

The correct answer is D

Step-by-step explanation:

the ratio of the sides of a right angle consisting of 30, 60 and 90 degrees is;

x : 2x : x

x  is the length of the side opposite angle 30, 2x is the length of the side opposite angle 90 and x is the length of the side opposite angle 60.

Considering this, from the diagram, 2x = 8cm,

hence, side q which corresponds to x will be 4

while side s which corresponds to x will be 4.
