I need to find cos of X. the triangle seems to be an obtuse scalene triangle. the hypotenuse is 12, since its the longest side. the adjacent angle i am guessing is 7 and the opposite has a length of 8.
\n" ); document.write( "---------------
\n" ); document.write( "If the side opposite angle x is 8, and the other sides are 7 and 12:
\n" ); document.write( " $\"12%5E2+=+7%5E2+%2B+8%5E2+-+2%2A7%2A8%2Acos%28x%29\"$
\n" ); document.write( "Solve for cos(x)
\n" ); document.write( "------
\n" ); document.write( "I don't know why you're guessing it's 7.
\n" ); document.write( "Also, hypotenuse applies only to right triangles.
\n" ); document.write( " \n" ); document.write( "
