Question

Find the measure of each missing angle

Angle 21 =


Angle 22 =


Angle 23 =


What is the sum of angles 21,22 and 23?

Answer 1

Explanation:

Angle 21 is calculated like this:

180 - 70 - 50 = 60 because a line is 180 degrees.

Angle 22 = 50 degrees because it is opposite to the upper angle of 50 degrees.

Angle 23 = 70 degrees because it is also opposite to the upper angle of 70 degrees.

The sum of the angles would be

60 + 50 + 70 = 180 degrees
