am i missing something in my answer?
- The shorter leg of a 30°- 60°- 90° right triangle is 7.5 inches. How long is the longer leg and the hypotenuse?
-The longer leg is 7.5 x √3 or 15/2 x √3 which can be written as 15x√3 divided by 2. The hypotenuse is 2 x 7.5 as well as 15

Learn this theorem

In a 30-60-90 triangle, the measure of the hypotenuse is two times that of the leg opposite the 30o angle.  The measure of the other leg is SQRT(3) times that of the leg opposite the 30o angle. 

The leg of the triangle opposite the 30 degree angle is the shortest side.

The 60 leg is √3 times the 30 leg which gives 7.5√3 or (15√3)/2.

The hypotenuse is twice the 30-leg is 2 times 7.5 = 15.
