If the base of the tent is 18 feet wide, then how tall is the tent? \n" ); document.write( "------------------------- \n" ); document.write( "Draw the equilateral triangle. \n" ); document.write( "Draw a perpendicular bisector from the top vertex to the base. \n" ); document.write( "You now have two right triangles. \n" ); document.write( "Use Pythagoras to solve for the height. \n" ); document.write( "EQUATION: \n" ); document.write( "h^2 + 9^2 = 18^2 \n" ); document.write( "h^2 = 18^2 - 9^2 \n" ); document.write( "h^2 = 243 \n" ); document.write( "height = sqrt243 = 15.59 feet \n" ); document.write( "============================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
