AngleT = 16x - 9 degrees
\n" ); document.write( " AngleU = 4x + 3 degreen
\n" ); document.write( " Given that T and U are compimentary
\n" ); document.write( " Therefore T + U = 90 degrees
\n" ); document.write( " That is (16x - 9) + (4x + 3 ) = 90
\n" ); document.write( "By addititve associativity and commutativity, we have
\n" ); document.write( " (16x + 4x) + ( -9 + 3 ) = 90
\n" ); document.write( " 20x - 6 = 90
\n" ); document.write( " 20x = 90 + 6 (by transposing, that is change side, then change sign)
\n" ); document.write( " 20x = 96
\n" ); document.write( " x = 96/20 = 4.8
\n" ); document.write( "Therefore Angle T = 16x - 9 = 16x4.8 - 9 = 76.8 - 9.0 = 67.8 degrees
\n" ); document.write( " And Angle U = 4x + 3 = 4x4.8 + 3 = 19.2 + 3.0 = 22.2 degrees
\n" ); document.write( "Verification:
\n" ); document.write( "T and U are Complimentary
\n" ); document.write( "T + U = 67.8 + 22.2 = 90 which is correct \r
