Is one angle is 30° then what is the measure of its complement

90-30=60

Step-by-step explanation:

The measure is 60°.

Complementary angles are adjacent angles which add to equal 90 degrees. Adjacent angles are angles which share a vertex and a side.

Since the sum of complementary angles is always 90°, you can subtract 30 from 90 to find the missing angle measure.

90 - 30 = 60

Answer:

The measure of its complement is 60°.
