Question

In AJKL, the measure of ZL=90°, JK = 7.3 feet, and KL = 4.7 feet. Find the measure

of ZJ to the nearest tenth of a degree.

Answer 1

40.1°

Explanation:

JK is the hypotenuse of the right triangle.

For angle J, KL is the opposite leg.

sin A = opp/hyp

sin J = 4.7/7.3

J = sin^-1 4.7/7.3

J = 40.1

Answer: 40.1°
