What is the supplementary angle of 20?

160∘
⇒ Supplementary angle of 20∘ is equal to 160∘.

What is the measure of the complement of the angle measuring 20?

R D Sharma – Mathematics 9 So if you have an angle that is 20 degrees, then the complement angle measures 70 degrees.

What is the sum of two supplementary angles?

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

What is the measure of the angle 20 70?

Example, 20° and 70° are complementary angles, because 20° + 70° = 90°.

What’s an angle measure?

An angle is a measure of the size of the opening of two lines that intersect. The VERTEX is the point of intersection, while the lines that form the opening are called the SIDES. The angles are measured in degrees. A Right Angle is 90 degrees or 1/4 of a circle.

Is an acute angle less than 90 degrees?

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

How do you find the measure of a supplementary angle?

Dividing both sides of the equation by 2, we can determine the measure of Angle B: Supplementary angles, by definition, add to to a sum of 180deg. The complement of an angle is 20° less than a third its supplement. What is the measure of the angle?

What is the measure of the other angle of the angles?

Supplementary Angles. Measure of the other angle is times . So, measure of the other angle is . If the sum of the measures of two angles is , then the angles are supplementary.

How do you find the supplement of a 20 degree angle?

To solve this, subtract 20 from both sides. Hence, the supplement of a 20˚ angle is a 160˚ angle. This can be proven again, since 20+160 = 180, and supplementary angles have a sum of 180˚.

Which angles of a linear pair are always supplementary?

The two angles of a linear pair , like ∠ 1 and ∠ 2 in the figure below, are always supplementary. But, two angles need not be adjacent to be supplementary.
