You can put this solution on YOUR website!
There's not enough information.
\n" ); document.write( "The sum of all of the angles equals 360.
\n" ); document.write( "\"2x%2By%2B2y-10%2B80%2B3x=360\"
\n" ); document.write( "\"5x%2B3y%2B70=360\"
\n" ); document.write( "\"5x%2B3y=290\"
\n" ); document.write( "You need to know something about the relationship of the angles.
\n" ); document.write( "If ABCD was a rhombus, parallelogram, square, or rectangle, you would know an additional relationship between x and y and be able to solve.
\n" ); document.write( "Right now you have 1 equation with 2 unknowns.
\n" ); document.write( "
\n" );
