Question

In ΔOPQ, the measure of ∠Q=90°, PO = 89, OQ = 39, and QP = 80. What ratio represents the cosine of ∠O?

Answer 1

39/89

Explanation:

no idea why the other said 38 instead of 89 but it is 39/89 according to what i have done

Answer 2

cos(O) = 39 / 89

Explanation:

Given:

ΔOPQ, where

• ∠Q=90°
• PO = 89
• OQ = 39
• QP = 80

cosine of ∠O?

• cos(O) = Adjacent / Hypotenuse

• cos(O) = 39 / 89
