if the sun is 28 degrees above the horizon, then, for all practical purposes, the building forms a triangle where the angle opposite the vertical building is equal to 28 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the building is the side opposite the angle and the length of the shadow on the ground is the side adjacent to the angle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the tangent of the angle is the side opposite the angle divided by the side adjacent to the angle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you let x equal the length of the side adjacent to the angle, then you get tangent of 28 degrees = 495 / x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for x to get x = 495 / tangent of 28 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "use your calculator to find that x = 930.9596003.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's the length of the shadow on the ground.\r
\n" ); document.write( "
