Find the measure of each missing angle Angle 21 =

Angle 22 =

Angle 23 =

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

Step-by-step 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

70
