An overhead wire stretches from the service drop that is 20ft from the ground,on a building to an insulator on a pole 35 ft from the ground. How long is the wire if the pole and building are 48 ft apart?(Assume ground is level.)Round answer to tenths.

\n" ); document.write( ".
\n" ); document.write( "From your diagram, you'll notice that the ground, building and pole forms a \"right triangle\". Because it is a right triangle (one of the interior angle of the triangle is 90 deg), we can apply Pythagorean theorem.

\n" ); document.write( "Let x = length of the overhead wire
\n" ); document.write( "then
\n" ); document.write( "x^2 = 48^2 + (35-20)^2
