Angle addition with relationships between angles calculator

This calculator is used to add and subtract angles in the form Degrees - Minutes - Seconds (DMS). Each degree is divided into 60 minutes, and each minute further divided into 60 seconds. This form is used in astronomy and defining latitude and longitude.

This is read as "34 degrees 24 minutes 16 seconds".

The calculator adds or subtracts input values from the running total in the top window.

Whenever a result is calculated it is also converted to decimal degrees. This is displayed just below the result window

A 'Supplementary Angle Calculator' is an online tool that finds and displays the supplementary angle of the given angle. Supplementary angles refer to the pair of angles that always sum up to 180°. These two angles are called supplements of each other.

What Is a Supplementary Angle Calculator?

In our Supplementary Angle calculator, you just need to enter the value of an angle that is less than 180°, to get its supplementary angle. Supplementary angles form a straight angle (180 degrees) when they are put together.

NOTE: Please Enter Values from 0 to 180 degrees.

How to Use the Supplementary Angle Calculator?

Follow these steps to use the calculator:

• Step 1: Enter any angle which is less than 180° in the input box.
• Step 2: Click on "Calculate" to find its supplementary angle.
• Step 3: Click on "Reset" to clear the field and enter the new value.

What Is a Supplementary Angle?

Two angles are said to be supplementary angles if their sum is equal to 180°.

In other words, ∠1 and ∠2 are supplementary if ∠1 + ∠2 = 180°

Therefore, if we know one angle, then we can easily find its supplementary angle by subtracting the given angle from 180°.

Solved Examples on Supplementary Angle Calculator

1. Example 1:

   Do the angles measuring 130° and 50° form a pair of supplementary angles?

   Solution:

   The sum of 130° and 50° is 180° .

   So, the angles measuring 130° and 50° form a pair of supplementary angles.

2. Example 2:

   Find the value of x such that x° and 75° form a pair of supplementary angles.

   Solution:

   If x° and 75° form a pair of supplementary angles, we will solve the equation x° + 75° = 180° to find the value of x.

   x° + 75° = 180°

    x° = 180° - 75° 

   x° = 105° 

   Therefore, the value of x is 105°, which is the supplementary angle of 75°.

Given angles of 130° and 3°, determine if they are complementary or supplementary

Are 130° and 3°complementary?

Two angles are complementary if their sum is equal to 90°

Angle 1 + Angle 2 = 130° + 3°
Angle 1 + Angle 2 = 133°

Since the sum of the two angles ≠ 90°, the two angles are not complementary

Are 130° and 3°supplementary?

Two angles are supplementary if their sum is equal to 180°

Angle 1 + Angle 2 = 130° + 3°
Angle 1 + Angle 2 = 133°

Since the sum of the two angles ≠ 180°, the two angles are not supplementary

What is the Answer?

Since the sum of the two angles ≠ 180°, the two angles are not supplementary

How does the Complementary and Supplementary Angles Calculator work?

This calculator determines the complementary and supplementary angle of a given angle that you enter OR it checks to see if two angles that you enter are complementary or supplementary.

What formulas are used for Complementary and Supplementary Angles?

IF an angle is less than 90°, then the complementary angle is 90 - θ
IF an angle is less than 1800°, then the supplementary angle is 180 - θ
