## What is the complementary angle of 2 degrees?

Angle 1 and angle 2 are complementary if the sum of both the angles is equal to 90 degrees (angle 1+ angle 2 = 90°) and thus, angle 1 and angle 2 are called complements of each other.

## What is the measure of complementary angle of?

90 degrees

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

**What is the complement and supplement of 2?**

The complement of an angle x is π2−x , so the supplement of 2 is π2−2≈−0.4292 .

**Which of the following pairs of angle measures are complementary?**

Two angles whose sum is 90° (that is, one right angle) are called complementary angles and one is called the complement of the other. Here, ∠AOB and ∠BOC are called complementary angles. ∠AOB is complement of ∠BOC and ∠BOC is complement of ∠AOB. Thus, the complementary angle of 60° is the angle measure 30°.

### What is the measure of complementary angle of 55?

In a triangle the complementary of an angle is = 90 degrees. since one angle is 55 degrees. Therefore answer is 35 degrees.

### When the sum of measure of two angles is 90?

complementary

Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.

**What angle is supplementary to 105?**

Thus, the supplement of angle 105° = 180° – 105° = 75°.

**How do you identify complementary and supplementary angles?**

Complementary angles form a right angle (L shape) and have a sum of 90 degrees. Supplementary angles form a straight line and have a sum of 180 degrees. If the relationship is given, you can subtract the given angle from the sum to determine the measure of the missing angle.

## How do you find the measure of each angle?

The formula for finding the total measure of all interior angles in a polygon is (‘’n’’ – 2) x 180, where ‘’n’’ is the number of sides, as well as the number of angles, the polygon has. Some common polygon total angle measures are as follows: The angles in a triangle (a 3-sided polygon) total 180 degrees.

## What is the formula for Complementary angles?

Formula to calculate the exterior angles in regular polygon is `360/n` . If we want to calculate the unknown angle in triangle means we can use sum of interior angle formula as A + B + C = 180. Formula to calculate the supplementary angle is A + B = 180. Formula to calculate the complementary angle is A + B = 90.

**What are examples of complementary angles?**

Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don’t have to be next to each other, just so long as the total is 90 degrees. Examples: • 60° and 30° are complementary angles. • 5° and 85° are complementary angles.

**How to find complementary angles?**

The complementary and supplementary of the two angles is decided by the sum of their measurement. If the sum of the two angles is equal to the measurement of a right angle then the pair of angles is said to be complementary angles. Two angles are said to be complementary angles if they add up to 90 degrees.
