You can put this solution on YOUR website!
x = measure of angle A
\n" ); document.write( "90 - x = complement of angle A {complementary angles add up to 90°}
\n" ); document.write( "180 - x = supplement of angle A {supplementary angles add up to 180°}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3(90 - x) = 180 - x - 60 {three times complement is 60 less than supplement}
\n" ); document.write( "270 - 3x = 120 - x {used distributive property on left, combined like terms on right}
\n" ); document.write( "150 - 3x = -x {subtracted 120 from both sides}
\n" ); document.write( "150 = 2x {added 3x to both sides}
\n" ); document.write( "x = 75 {divided both sides by 2}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle A = 75°
\n" ); document.write( "
