Question

In AMNO, the measure of 20=90°, MN = 99 feet, and OM = 52 feet. Find the

measure of M to the nearest degree.

Answer 1

x = 58 degrees

Explanation:

Using the SOH CAH TOA trigonometry identity

hypotenuse =99

adjacent = 52

angle of elevation = x

cos theta = adj/hyp

cos x = 52/99

x = arccos (52/99)

x = arccos(0.5253)

x = 58 degrees ( to the nearest degree)
