Answer:
A. 9
Step-by-step explanation:
This is a 30° 60° 90° special triangle
The side lengths should go as x (across the 30°) x√3 (across the 60°) 2x (across the 90°)
if a which is comes across 30° is = 3√3 that means x is 3√3
b which is comes across the 60° must be √3 times of what comes across the 30° therefore the value of b is
3√3 × √3 = 9
