Complementary Angles - GED Math

Two angles are complementary when they add up to .

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.

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 42 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 84 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 46 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 78 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 72 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 3 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 51 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 37 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 81 degrees for angle B.

Two angles are classified as complementary if an only if the sum of the angles equals to exactly 90 degrees.

Since we know the measurement of one angle, and we know the rule about complementary angles, let's find the other angle:

The other angle is simply the total sum of both angles minus the given angle.
The total sum of the angles is , and the given angle is .

So, we will subtract from .

Other angle=

The other angle has a measurement of degrees.

The definition of a complementary angle means that two angles must add up to 90 degrees.

To find the angle, simply subtract 55 from 90.

The answer is:

The sum of complementary angles is equal to .

Set up the following equation and solve for :

and form a linear pair, so their measures add up to that of a straight angle, which is . They must be supplementary (and cannot be complementary).

and are a pair of vertical angles - angles formed from a pair of intersecting lines which together have the lines as the union. They must be congruent, and need not be complementary.

and are a pair of same-side interior angles formed by transversal across the parallel lines. They must be supplementary (and cannot be complementary).

and are the acute angles of right triangle . They must be complementary. This is the correct pair.

Since angles A and B are complementary angles, their measurements add up to equal 90. Therefore, we need to set up our equation as follows:

Combine like terms:

And solve for :

Since angles A and B are complementary, their measures add up to 90 degrees. Therefore we can set up our equation as such:

-or-

Combine like terms and solve for :
