Question

In ΔOPQ, the measure of ∠Q=90°, PQ = 1.8 feet, and OP = 7.4 feet. Find the measure of ∠P to the nearest degree.

Answer 1

P=75.922 ≈ 76

∘Explanation:

What function uses the ADJACENT and the HYPOTENUSE?

SOH-CAH-TOA

cos P = adjacent/hypotenuse= 1.8/7.4

Pcos^-1 = (1.8/ 7.4)

​

P=75.922 ≈ 76
