What is the measure of two complementary angles if one angle measures twice the other?

2 Answers By Expert Tutors Complementary angles total 90-degrees. Solving for x, we get x = 30. Since the first angle was called x, that means it’s measurement is 30°. The second angle, 2x, is just twice the first angle, so its measurement is 60°.

How do you find the angle of two complementary angles?

How to Find a Complementary Angle? Since we know that complementary angles add to 90 degrees, we can easily calculate the value of any angle by subtracting the given angles from 90 degrees. Calculate the complement angle of 33°. Subtract the given angle from 90°.

What is the sum of 2 complementary angles?

90 degrees
Consider two complementary angles: A and another angle. A and ( Another Angle ) Since they are complementary, they add up to 90 degrees. A + ( Another Angle ) = 90 Notice that we call angle A by its name: “A”.

How do you find the measure of another angle?

The best way to measure an angle is to use a protractor. To do this, you’ll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle’s measurement to the nearest degree.

Which pair of the following angles are complementary?

Complementary Agnles: When the sum of two angles is equal to 90o, they are called complementary angles. In this case, both angles are called complementary to each others. For example 30o and 60o, 40o and 50o, 20o and 70o, etc. are complementary angle since their sum is equal to 90o.

What is the complementary angle of 60?

30°
The complementary angle of 60° is 30°.

Which of the pairs of angles are complementary?

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.

Which of the following pairs of angles are not complementary?

Explanation: Complementary angle pairs’ sum is always 90° . 160° and 30° added up is 190°. So, it’s not a pair of complementary angles.

What are the 5 angles?

The types are:

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