The diagonal is the hypotenuse.\r
\n" ); document.write( "\n" ); document.write( "the legs are 150 ft and 320 ft\r
\n" ); document.write( "\n" ); document.write( "their squares are 22500 ft^2 and 102400 ft^2\r
\n" ); document.write( "\n" ); document.write( "The sum of those two (Pythagorean theorem) is 124900 ft^2\r
\n" ); document.write( "\n" ); document.write( "The sqrt(124900)=353.41 ft\r
\n" ); document.write( "\n" ); document.write( "The angle with the sideline is the tangent, and it is (150/320)= 0.46875 The arc tan gives 25.1 degrees\r
\n" ); document.write( "\n" ); document.write( "The angle with the end line is the cotangent, but we have two angles , 90 and 25.1, and the third angle is 180 - (115.1) = 64.9 deg\r
