Algebra.Com's Answer #455722 by timvanswearingen(106)![]() ![]() You can put this solution on YOUR website! The height would be drawn from a vertex to the midpoint of the opposite side. Setting up a right triangle and using the Pythagorean Theorem:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The height is:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Area is 1/2*base*height. The base is 10 and we just found the height:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( " |
