Question

formula to find the length of one side of a triangle​

Answer 1

Multiply the sine of angle B by the length of the side opposite angle A (side A). For the example, if side A measured 10 inches: 0.71 x 10 = 7.1. Divide this number by the sine of angle A to find the length of side B. For the example, angle A measured 30: sine 30 = 0.5: 7.1/0.5 = 14.2 inches for the length of side B.

Answer 2

Answer:

Multiply the sine of angle B by the length of the side opposite angle A (side A). For the example, if side A measured 10 inches: 0.71 x 10 = 7.1. Divide this number by the sine of angle A to find the length of side B. For the example, angle A measured 30: sine 30 = 0.5: 7.1/0.5 = 14.2 inches for the length of side B.
