Question 312974: in triangal PQR, m angleQ = 90 degrees, RQ = 3 and RP = 5 what is cos P
Answer by nyc_function(2741)   (Show Source):
You can put this solution on YOUR website! To find cos(p), we need to know that cosine = adjacent side divided by hypotenuse. We know that the adjacent side is PQ and the hypotenuse is 5.
However, we are not given side PQ. To find PQ, we use the Pythagorean Theorem.
I found PQ to be 4.
Then cos(p) = 4/5
