\n" ); document.write( "\n" ); document.write( "Assume your triangle has hypotenuse , side opposite the 43 degree angle of , and the third side .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since the sum of the two acute angles of any right triangle must be 90, the third angle in this triangle is 47 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "From the trigonometry of a right triangle we know that the measure of side is given by , the measure of side is given by , and the measure of the hypotenuse is simply , hence:\r
