The height of the pole and the ground distance from the pole are legs in a right triangle.
\n" ); document.write( "The hypotenuse is the length of of the wire from the top of the pole to the ground.
\n" ); document.write( "Use the Pythagorean theorem.
\n" ); document.write( " $\"H%5E2=10%5E2%2B15%5E2\"$
\n" ); document.write( " $\"H%5E2=100%2B225\"$
\n" ); document.write( " $\"H%5E2=325\"$
\n" ); document.write( " $\"H=sqrt%28325%29\"$
\n" ); document.write( " $\"H=5sqrt%2813%29\"$ or approximately
\n" ); document.write( "H=18.0 ft \n" ); document.write( "
