The size of the given angle is approximately 200°
What is measure of angle?
- "It is the measurement of the angle formed by the two rays or arms at a common vertex"
- Angles are measured in degrees using a protractor.
For given question,
We need to find the size of angle.
We know, the sum of all angles on either side of the line is 180°
If we continue the straight line towards right, then the part of the angle above line must be 180°
To find the angle below straight line,
Put the protractor at the vertex of both the line segments and measure the angle.
The angle must be within the range 15° - 25°.
Let the angle below straight line is 20°
So, the total angle is 180° + 20° = 200° (approximate size)
Therefore, the size of the given angle is approximately 200°
