there is a diagram of a triangle
\n" ); document.write( "one side is = 1, another side is = 4 and there is 100 degree angle
\n" ); document.write( "which is opposite side C.
\n" ); document.write( "I am looking for the value of side C\r
\n" ); document.write( "\n" ); document.write( "-----------------------------------
\n" ); document.write( "C would be the 3rd side.
\n" ); document.write( "Use the Law of Cosines:
\n" ); document.write( "c^2 = a^2 + b^2 - 2ab*cos(C)
\n" ); document.write( "c^2 = 1^2 + 4^2 -2*1*4*cos(100)
\n" ); document.write( "c^2 = 1.38918...
\n" ); document.write( "c = 4.28826...
