Question

Find the complement of the angle measuring 60 degrees.

• A. 30 degrees
• B. 40 degrees
• C. 50 degrees
• D. 80 degrees

Answer 1

The correct option is A 30 degrees

When the sum of the measures of two angles is 90 degrees, the angles are called complementary angles.

Let the measure of the complement of the angle measuring 60 degrees be a degrees.

So, (a + 60) degrees = 90 degrees
Hence, a = (90 - 60) degrees = 30 degrees
