How do I find the measure of an 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.

What's an angle in math?

• In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle.
• The word “angle” is derived from the Latin word “angulus”, which means “corner”.
• The two rays are called the sides of an angle, and the common endpoint is called the vertex.

What is the measure right angle?

• Right angles measure 90 degrees.
• Obtuse angles measure more than 90 degrees.

According to the question:

70+40+ x = 180.

110 + x = 180.

x = 180 - 110.

x = 70.

Hence, 70 is  measure of red angle.
