Algebra.Com's Answer #223793 by nyc_function(2741) 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.\r \n" ); document.write( "\n" ); document.write( "However, we are not given side PQ. To find PQ, we use the Pythagorean Theorem.\r \n" ); document.write( "\n" ); document.write( "I found PQ to be 4.\r \n" ); document.write( "\n" ); document.write( "Then cos(p) = 4/5 \n" ); document.write( " |
