Question

In ΔJKL, the measure of ∠L=90°, the measure of ∠J=9°, and KL = 49 feet. Find the length of JK to the nearest tenth of a foot.

Answer 1

Explanation:

313.2

Answer 2

in triangle KLJ

relationship between perpendicular and hypotenuse is given by sin angle

sin9°=p/h

sin9=KL/KJ

sin9=49/x

x=49/sin9=313.2

the length of JK to the nearest tenth of a foot is 313ft
