Question #N269
In a right triangle, one angle 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. 20
Correct Answer is: A
A 30-60-90 right triangle has special side ratios. The hypotenuse is twice the length of the shorter leg. Therefore, the shorter leg is half the length of the hypotenuse, which is 10 / 2 = 5.
