Question #N121
In a right triangle, one of the acute angles measures 30 degrees. If the hypotenuse has a length of 10, what is the length of the shorter leg?
A. 5
B. 5\sqrt{3}
C. 10\sqrt{3}
D. 10\sqrt{2}
Correct Answer is: A
In a 30-60-90 right triangle, the shorter leg is half the length of the hypotenuse. Since the hypotenuse is 10, the shorter leg has a length of 10/2 = 5.
