Answer:
cos(P) = 20/29
Step-by-step explanation:
Given the following information:
To ratio represents the cosine of ∠P we use the cosine law (please have a look at the attached photo)
=+ − 2QP*PRcos(P)
<=> cos(P) = (+ - ) / 2QP*PR
<=> cos(P) =( ) /2*29*20
<=> cos(P) = 20/29
Hope it will find you well.
