\n" ); document.write( "I assume you meant the \"bottom length\" is 10.
\n" ); document.write( ".
\n" ); document.write( "because you know two of the three angles, you can determine the third angle as:
\n" ); document.write( "180-(90+65) = 25 degrees
\n" ); document.write( ".
\n" ); document.write( "You can apply cosine:
\n" ); document.write( "cos = adjacent/hypotenuse
\n" ); document.write( "cos(65) = 10/x
\n" ); document.write( "x = 10/cos(65)
\n" ); document.write( "x = 23.66
\n" ); document.write( ".
\n" ); document.write( "Or, you can apply sine:
\n" ); document.write( "sin = opposite/hypotenuse
\n" ); document.write( "sin(25) = 10/x
\n" ); document.write( "x = 10/sin(25)
\n" ); document.write( "x = 23.66
\n" ); document.write( " \n" ); document.write( "
