Answer:

Step-by-step explanation:

The lengths of the sides of a 30-60-90 triangle are in the ratio 1:√3:2.

Let the length of the side opposite the 30° angle be 1, then the length of the side opposite the 60° angle is √3, and the length of the hypotenuse is 2.

sin(30°) = (leg opposite the 30° angle)/hypotenuse = 1/2

cos(60°) = (leg adjacent to the 60° angle)/hypotenuse = 1/2
