Question

Find each angle measure. SEE EXAMPLE 3 19. m21 20. m22 2. 123° 1 SOWAT

Answer 1

Step-by-step explanation:

as , sum of both the angles on the same side of transversal is 180°

so,

Angle 2 + angle 5 = 180°

123° + angle 2 = 180°

Angle 2 = 180° - 123° = 57°

angle 2 = 57°

and

angle 1 = 123° ( Alternate Interior Angle )

hope this answer helps you dear...take care!
