Question

In AMNO, the measure of Z0=90°, the measure of ZM=13°, and OM = 9.6 feet. Find

the length of MN to the nearest tenth of a foot.

Answer 1

Hypotenuse MN = 10.54 ft (Approx.)

Explanation:

Given:

Base OM = 9.6 ft

Angle θ = 13'

Find:

Hypotenuse MN

Computation:

Using trigonometry function

Cos θ = Base / Hypotenuse

Cos 13 = 9.6 / Hypotenuse

0.97 = 9.6 / Hypotenuse

Hypotenuse MN = 10.54 ft (Approx.)
