What is the 30°-60°-right triangle theorem?

A) In a right triangle, the hypotenuse is three times as long as a leg if and only if the measure of
the angle opposite that leg is 30°.

B) In a right triangle, the hypotenuse is twice as long as a leg if and only if the measure of the
angle opposite that leg is 60°.

C) In a right triangle, the hypotenuse is twice as long as a leg if and only if the measure of the
angle opposite that leg is 30°.

D) In an equilateral triangle, the hypotenuse is twice as long as a leg if and only if the measure of
the angle opposite that leg is 30°.
