The measure of angle b, the supplement of angle a, is four times the measure of angle c, the complement of angle a\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1. Supplementary angles means two angles add up to 180 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 2. Complementary angles means two angles add up to 90 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 3. Let a be the angle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 4. Let b=180-a be the supplement of the angle a.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 5. Let c=90-a be the complement of the angle a.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 6. Then 180-a= 4(90-a) the measure of angle b, the supplement of angle a, is four times the measure of angle c, the complement of angle a.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 7. Simplifying Step 6 yields the following steps:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"180-a=+360-4a\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Add 4a-180 to both sides of the equation to get variable a in left side and numbers on right side.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"180-a%2B4a-180=360-4a%2B4a-180\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3a=180\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide 3 to both sides of the equation\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3a%2F3=180%2F3\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"a=60\" \"180-a=120\" and \"90-a=30\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check if equation in Step 6 is true...180-a= 4(90-a) or 120=4*30 which is a true statement.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 7. ANSWER: Angle is 60 degrees, its supplementary angle is 120 degrees, and its complementary angle is 30 degrees\r
