Algebra.Com's Answer #151004 by nerdybill(7384) You can put this solution on YOUR website! height is 8 feet, base across is 12 feet, what is the lenght of the triangle? \n" ); document.write( "It looks like an isoceles triangle. \n" ); document.write( ". \n" ); document.write( "Find the length via the Pythagorean theorem where \n" ); document.write( "length of triangle is the hypotenuse \n" ); document.write( "height is one side \n" ); document.write( "half the base is the other side \n" ); document.write( ". \n" ); document.write( "Let x = length of triangle \n" ); document.write( "8^2 + 6^2 = x^2 \n" ); document.write( "64 + 36 = x^2 \n" ); document.write( "100 = x^2 \n" ); document.write( "sqrt(100) = x \n" ); document.write( "{-10, 10} = x \n" ); document.write( "Throw out negative answer: \n" ); document.write( "10 feet =x \n" ); document.write( " \n" ); document.write( " |
