One of two Supplementary angles is four times the other. Find the larger one.

Step 1. Supplementary angles add up to 180 degrees.

Step 2. Let x the angle and 4x be its supplementary angle.

Step 3. Then x+4x=180 or 5x=180. Divide by 5 to both sides to get x=36 degrees. With x=36 then 4x=144 degrees.

Step 4. ANSWER: The larger supplementary angle is 144 degrees.

I hope the above steps were helpful.
