# What is the measure of 9 angle?

## What is the measure of 9 angle?

9. Angle = 1/3956 = 0.0002528 radians = 0.01448° = 0.8690′ = 52.14″.

### How do you find the larger angle supplementary?

How to Find Supplementary Angles? We can calculate supplementary angles by subtracting the given one angle from 180 degrees. To find the other angle, use the following formula: ∠x = 180° – ∠y or ∠y = 180° – ∠x where ∠x or ∠y is the given angle.

What does 2 supplementary angles make?

180°
The sum of the measures of two supplementary angles is 180° .

Can two supplementary angles have the same measure?

Supplementary angles add up to \begin{align*}180^\circ\end{align*}. Congruent angles have the same measure. So, \begin{align*}180^\circ \div 2 = 90^\circ\end{align*}, which means two congruent, supplementary angles are right angles, or \begin{align*}90^\circ\end{align*}.

## What is a 100 degree angle called?

An obtuse angle is a type of angle whose degree measurement is more than 90° but less than 180°. Examples of obtuse angles are: 100°, 120°, 140°, 160°, 170°, etc. ∠ PQR is an obtuse angle because it’s less than 180° and greater than 90°.

### What is the name of 180 degree angle?

straight angles
Angles that are 180 degrees (θ = 180°) are known as straight angles. Angles between 180 and 360 degrees (180°< θ < 360°) are called reflex angles.

How do you know if an angle is supplementary?

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 is a supplementary angle example?

Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°. Similarly, complementary angles add up to 90 degrees.

## Are supplementary angles always congruent?

No, supplementary angles are not always congruent, and we can demonstrate this by showing an example of two supplementary angles that are not congruent, meaning they do not have the same measure. Therefore, any two angles with measures that sum up to 180° are supplementary.

### How do you know if angles are congruent or supplementary?

Congruent segments are segments that have the same length. Two angles are complementary if the sum of their measures is 90. Two angles are supplementary if the sum of their measures is 180.

What are the 5 types of angles?

Types of Angles – Acute, Right, Obtuse, Straight and Reflex Angles

• Acute angle.
• Right angle.
• Obtuse angle.
• Straight angle.
• Reflex angle.

What is a zero angle?

Zero Angles An angle with a measure of zero degrees is called a zero angle. If this is hard to visualize, consider two rays that form some angle greater than zero degrees, like the rays in the . Then picture one of the rays rotating toward the other ray until they both lie in the same line.

## How to find the larger of two supplementary angles?

The larger of two supplementary angles exceeds seven times the smaller by four degrees. FInd the measure of the larger angle . The problem expects that you know the definition of “supplementary”. If two angles are supplementary, the sum of their angles equal 180.
