Question #N87
In a right triangle, one angle measures 30 degrees and the hypotenuse has a length of 10. What is the length of the side opposite the 30-degree angle?
A. 2
B. 5
C. 5\sqrt{3}
D. 10\sqrt{3}
Correct Answer is: B
A 30-60-90 right triangle has sides in the ratio of 1:√3:2. Since the hypotenuse has a length of 10, the side opposite the 30-degree angle has a length of 10 / 2 = 5.
