Two telephone poles are 60 meters apart.the poles are 42 metres and 69 metres high.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the difference between the lengths of poles = 27 m\r
\n" ); document.write( "\n" ); document.write( "the distance between them = 60 m\r
\n" ); document.write( "\n" ); document.write( "the poles are vertical\r
\n" ); document.write( "\n" ); document.write( "Apply Pythagorean Theorem\r
\n" ); document.write( "\n" ); document.write( "One leg 60 m
\n" ); document.write( "Second leg 27 m
\n" ); document.write( "Hypotenuse x m
\n" ); document.write( "By Pythagoras theorem
\n" ); document.write( "Hypotenuse^2 = Leg1^2+leg2^2
\n" ); document.write( "\"%09x+%09%5E2%09=%0960%09%5E2%09%2B%0927%09%5E2\"
\n" ); document.write( "x ^2 = 3600 + 729
\n" ); document.write( "x ^2 = 4329
\n" ); document.write( "\"+sqrt%28x%5E2%29=%09%09sqrt%28%094329%09%29\"
\n" ); document.write( "x= 65.8 m
\n" ); document.write( "the distance between their tops is 65.8 m\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
