Quetlon 21 of 28Which of the following represents the ratio of the hypotenuse to the short legfor the triangle shown below?30°60°A. 2:1B. 1: 5C. 3:1D. 1:2

Answer 1

In order to determine the ratio of the hypotenuse to the short leg, use the sine of angle 30°:

sin 30° = opposite side / hypotenuse

Take intop account that sin30° is jsut the same the required ratio.

Moreover, consider that sin 30° = 1/2, which is the same that:

opposite side / hypotenuse = 1/2

or

hypotenuse / opposite
