The bed is the hypotenuse of a right triangle.
\n" ); document.write( "The side opposite the angle of elevation is the height.
\n" ); document.write( "\"sin%28theta%29=OPP%2FHYP\"
\n" ); document.write( "\"H=HYP%2Asin%28theta%29\"
\n" ); document.write( "\"H=15%2Asin%2830%29=15%2F2\"\"ft\"
\n" ); document.write( "Substitute for the other two angles to get the two heights.
\n" ); document.write( "
\n" );
