Answer:
Step-by-step explanation:
This is a 30-60-90 triangle. Remember the lengths of the sides of a 30-60-90 triangle are in the ratio 1:√3:2
The side opposite the 90° angle has length 12, so the side opposite the 30° angle has length 6, and the side opposite the 60° angle has length 6√3.
x = 6√3 units
