Three times the measure of the angle is twice that of its complement.

Step 1. Complementary angles means that two angles add up to 90 degrees.

Step 2. Let x be the angle and 3x be three times the angle.

Step 3. Let 90-x be its complement and 2(90-x) be twice its complement.

Step 4. Then 3x=2(90-x) since three time the measure of the angle is twice that of its complement.

Step 5. Solving yields the following steps:

Done!



Then x=36 and 90-x=54

Check 3x=2(90-x) or 3*36=2*54...which is a true statement.

Step 6. ANSWER: The angles are 36 and 54 degrees

I hope the above steps were helpful.
