\r
\n" ); document.write( "\n" ); document.write( "The height bisects the base
\n" ); document.write( "Base = 10
\n" ); document.write( "so half the base = 5 cm
\n" ); document.write( "hypotenuse = 20\r
\n" ); document.write( "\n" ); document.write( "The congruent side the height and half the base will form a right triangle.
\n" ); document.write( "The congruent side is the hypotenuse.\r
\n" ); document.write( "\n" ); document.write( "height is the other leg\r
\n" ); document.write( "\n" ); document.write( "Pythagoras theorem
\n" ); document.write( "
\n" ); document.write( "(Hyp)^2= (leg1)^2+ Leg2^2
\n" ); document.write( "Hypotenuse = 20 ft
\n" ); document.write( "leg1= 5 ft
\n" ); document.write( "Leg2= ?
\n" ); document.write( "
\n" ); document.write( "leg2^2=hyp^2-leg1^2
\n" ); document.write( "Leg2^2= 20 ^2 - 5 ^2
\n" ); document.write( "Leg2^2= 400 - 25
\n" ); document.write( "Leg2^2= 375
\n" ); document.write( "Leg2= \"sqrt%28175%29\"
\n" ); document.write( "height= 19.36 ft\r
