Algebra.Com's Answer #185219 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! To form the altitude we form a right angle and bisect the base. \n" ); document.write( "so one leg is 1/2 the base which is 1/2*8 the hypotenuse is 8 \n" ); document.write( "so we have a^2+b^2=c^2 \n" ); document.write( "where a=8/2=4 and c=8 \n" ); document.write( "4^2=16 \n" ); document.write( "and 8^2=64 \n" ); document.write( "so we have 16+b^2=64 \n" ); document.write( " solve for b \n" ); document.write( " \n" ); document.write( " |
