Question

The measure of an angle is 48.1°. What is the measure of its complementary angle?

This is in IXL

Answer 1

Answer: 41.9

Explanation:

A complementary angle is an angle in which when you add another angle measure, you will get 90. For example, 60 + 30 = 90, 30 is a complementary angle, as is 60.

So, for this question in particular, you can set up the equation 48.1 + x = 90. Solve for x by subtracting 90 by 48.1, and the answer will be 41.9.
