Algebra.Com's Answer #89812 by algebrapro18(249) ![]() You can put this solution on YOUR website! Here you going to want to use cosine. \r \n" ); document.write( "\n" ); document.write( "the base of the triangle created by the latter and the wall is x and the hypontenuse is 15 feet so that sets up this trig ratio: \r \n" ); document.write( "\n" ); document.write( "cos 65 = x/15 \r \n" ); document.write( "\n" ); document.write( "now we just need to solve for x \r \n" ); document.write( "\n" ); document.write( "cos 65 = x/15 --> multiply both sides by 15 \n" ); document.write( "15 cos(65) = x --> approximate the value of x \n" ); document.write( "6.3 = x \n" ); document.write( " |
