What is the measure of an angle supplementary to 80 degrees?

Answer and Explanation: The supplementary angle of 80° is 100°.

What kind of angle is the 80 degree angle?

Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.

Is 80 complementary or supplementary?

(i) Angles of measure 100° and 80° are supplementary angles because 100° + 80° = 180°. Thus the supplementary angle of 80° is the angle of measure 100°. Working rule: To find the supplementary angle of a given angle, subtract the measure of angle from 180°.

What will be the measure of each angle formed after bisecting an angle of 80 degree?

So the measure of each parts of the bisected angle is ∠AOX=∠BOX=40o.

What's an supplementary angle?

Definition of supplementary angles

: two angles or arcs whose sum is 180 degrees.

Finding the complement and supplement for an angle in degrees

What angles add up to 90?

In geometry, complementary angles are defined as two angles whose sum is 90 degrees. In other words, two angles that add up to 90 degrees are known as complementary angles. For example, 60° and 30°.

What angle adds up to 180?

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

What angle equals 180 degrees?

Angles that are 180 degrees (θ = 180°) are known as straight angles.

What is a 90-degree angle called?

In geometry and trigonometry, a right angle is an angle of exactly 90 degrees or. 2 radians corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.

Which of the following is the supplement of an angle 38 *?

The supplement of 38 degrees is thus : 180 - 38 = 142 degrees. the answer = 142 degrees.

How do you draw 180?

How to Draw 180 Degree Angle?

1. Step 1: Draw a ray OA.
2. Step 2: Place the protractor at point O.
3. Step 3: In the inner circle of the protractor, look for 180° reading and with a pencil mark a dot and name it C.
4. Step 4: Join O and C. Now, ∠AOC=180 degree angle.

How do you 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.

Are all triangles 180 degrees?

The three interior angles of a triangle will always have a sum of 180°. A triangle cannot have an individual angle measure of 180°, because then the other two angles would not exist (180°+0°+0°). The three angles of a triangle need to combine to 180°.

Which of the following is the supplement of an angle measure 60?

The supplementary angle of 60∘ is 120∘ .

What is the complement of a 50 angle?

The complement of 50° is the angle that when added to 50° forms a right angle (90° ).

Do triangles add up to 180 or 360?

Angles in a triangle sum to 180° proof.

Does a triangle equal 90?

Explanation: The interior angles of a triangle always add up to 180 degrees. We are given angle and since this is indicated to be a right triangle we know angle is equal to 90 degrees.

Why is a circle 360 degrees?

A full circle is 360 degrees because the Babylonians used the sexagesimal system. It also represents the number of days a year and also because 360 is highly composite.

What is the supplementary angle of 87?

Hence, the supplement of 87° is 93°.

What is the supplement of 40 degrees?

Answer and Explanation: The supplement of a 40° angle is a 140° angle.

What is the supplementary angle of 65?

Supplementary angles are those whose sum equals 180°. Let the complement angle of 65° be x. Let the supplement angle of 65° be y. Ans : Complement of 65° is 25° and Supplement is 115°.

What is a 189 degree angle called?

obtuse angle-an angle between 90 and 180 degrees.

What is the name of 120 degree angle?

An obtuse angle can also be found out if we have the measure of the acute angle. In the picture above, line segment DO intersects line segment OQ at point O and forms an angle DOQ measuring 120°. Thus, it is an obtuse angle.
