If the set of angles are complementary, they must add up to  radians, which is equivalent to 90 degrees.

Subtract  radians from  radians.

The answer is:  

Complementary angles must sum up to 90 degrees. In order to find the other angle, we must subtract the given angle from 90 degrees.

The answer is:  

Which of the following pairs of angles are complementary angles?

Recall that complementary angles are angles which add up to 90 degrees.

In this case, all we have to do is see which pairs sum to 90, and that will be our answer:

So it must be the last one.

No calculation is actually required for this problem. is the right angle of , so and must comprise a complementary pair of angles. Since is complementary to , any angle complementary to  must have measure equal to that of , which is .

With the provided image, we are asked to solve for the measure of the unknown angle.

First, we must understand some information before attempting to solve the problem. The problem provides the information that the two angles summed up result in a complimentary angle. This is another way to say that when we add the measures of the two angles, it will equal .

This becomes a problem where we solve for a missing variable now. We can call the unknown angle x. We would set this up in equation format accordingly:

Now, we can solve for x. 

Therefore, the unknown angle is .

Which of the following angles forms a complementary angle pair with ?

Given that 

Complementary angles sum up to 90 degrees. Therefore, to find our answer, we simply need to do the following:

So, our answer is 33 degrees

If two angles are complementary, that means the sum of their degrees of measure will add up to 90. In order to find the measure of angle B, subtract angle A from 90 like shown:

This gives us a final answer of 15 degrees for angle B.

If two angles are complementary, that means the sum of their degrees of measure will add up to 90. In order to find the measure of angle B, subtract angle A from 90 like shown:

This gives us a final answer of 63 degrees for angle B.
