If the shortest leg of a 30-60-90 triangle has length 7, the length of the hypotenuse is __________.?

the answer is 14. the theorem is: in a 30-60-90 triangle, when the shortest leg is x, the hypotenuse is 2x, and the other leg is x rad 3. so, since the shortest leg is 7, the hypotenuse is 2x=2(7)=14.
