Explanation:
This is a 30-60-90 triangle. The short leg is always opposite the 30 degree angle. The long leg is opposite the 60 degree angle.
For these types of special triangles, we can say
Based on that formula, and the fact that the long leg is
, this means the short leg must be 6 units long.
For any 30-60-90 triangle, the hypotenuse is twice as long as the short leg
So the hypotenuse is 2*6 = 12 units long
