Some of but NOT a finished solution:\r
\n" ); document.write( "\n" ); document.write( "Draw the described figure. YZ along the ground, YE a hypotenuse;
\n" ); document.write( "Triangle YZE.
\n" ); document.write( "On top of that triangle another sharing side YE with the on-the-ground triangle, triangle XYE.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "YZ = 12;
\n" ); document.write( "ZE = 1.5
\n" ); document.write( "X is top of the pole. Y is on the ground.
\n" ); document.write( "m of angle YZE is 90 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"YE=sqrt%281.5%5E2%2B12%5E2%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"sin%28EYZ%29%2F1.5=sin%2890%29%2FYE\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"sin%28EYZ%29=1.5%2Fsqrt%281.5%5E2%2B12%5E2%29\"
\n" ); document.write( "from which find
\n" ); document.write( "m of angle \"EYZ=+arcsin%281.5%2Fsqrt%281.5%5E2%2B12%5E2%29%29\"\r
\n" ); document.write( "\n" ); document.write( "and from that find
\n" ); document.write( "measure of angle XYE = \"90-arcsin%281.5%2Fsqrt%281.5%5E2%2B12%5E2%29%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You want to solve for XY.
\n" ); document.write( "You would now have found known:
\n" ); document.write( "meas angle XYE;
\n" ); document.write( "meas angle YEX (fifty degree);
\n" ); document.write( "length YE;
\n" ); document.write( "AND YOU CAN COMPUTE ANGLE YXE having now already two of the upper triangles angle measures.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "From there use Law Of Sines to find XY.
