The legs of a ladder are of equal length and are 1 meter apart. the slant height of the ladder is 2.4 metres. how high above the ground does the ladder reach? \n" ); document.write( "---- \n" ); document.write( "You have an isosceles triangle with base = 1 meter, \n" ); document.write( "each side is 2.4 meters. \n" ); document.write( "---- \n" ); document.write( "Draw the height as a perpendicular bisector of the base. \n" ); document.write( "--- \n" ); document.write( "Use Pythagoras to find the height. \n" ); document.write( "---- \n" ); document.write( "slant height ^2 = height^2 + base^2 \n" ); document.write( "------ \n" ); document.write( "2.4^2 = h^2 + (1/2)^2 \n" ); document.write( "--- \n" ); document.write( "h^2 = 5.76 - 0.25 \n" ); document.write( "--- \n" ); document.write( "h^2 = 5.51 \n" ); document.write( "height = 2.35 meters \n" ); document.write( "========================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "=========== \n" ); document.write( " \n" ); document.write( " |
