You can put this solution on YOUR website!
As soon as you see the word complementary, you must know that the angles add up to 90 degrees.\r
\n" ); document.write( "\n" ); document.write( "angle A + angle B = 90\r
\n" ); document.write( "\n" ); document.write( "angle A = 9 less than TWICE angle B. We don't know what angle B is, right? I will say that angle B = x.\r
\n" ); document.write( "\n" ); document.write( "angle A = 2x - 9\r
\n" ); document.write( "\n" ); document.write( "We now have this equation:\r
\n" ); document.write( "\n" ); document.write( "2x - 9 + x = 90\r
\n" ); document.write( "\n" ); document.write( "Solve for x.\r
\n" ); document.write( "\n" ); document.write( "3x - 9 = 90\r
\n" ); document.write( "\n" ); document.write( "3x = 90 + 9\r
\n" ); document.write( "\n" ); document.write( "3x = 99\r
\n" ); document.write( "\n" ); document.write( "x = 99/3\r
\n" ); document.write( "\n" ); document.write( "x = 33\r
\n" ); document.write( "\n" ); document.write( "The measure of angle A = 2(33) - 9.\r
\n" ); document.write( "\n" ); document.write( "angle A = 66 - 9\r
\n" ); document.write( "\n" ); document.write( "angle A = 57 degrees\r
\n" ); document.write( "\n" ); document.write( "===================================\r
\n" ); document.write( "\n" ); document.write( "angle B = x and I just found that x = 33, right?\r
\n" ); document.write( "\n" ); document.write( "Then, angle B = 33 degrees.\r
\n" ); document.write( "\n" ); document.write( "How do you know that I am right?\r
\n" ); document.write( "\n" ); document.write( "When adding 33 + 57, I get 90 degrees ON BOTH SIDES of the equation.\r
\n" ); document.write( "\n" ); document.write( "Did you follow?\r
\n" ); document.write( "\n" ); document.write( "NOTE: If you see a similar question saying that two angles are supplementary, this means that both angles, when added, will produce 180 degrees. I give you this information now because most likely you will a question like that in your math course.\r
