Geometry math question

Answer 1

Since Angle 1 and 3 are vertical angles, they are congruent.

In this case, because Angle 1 is 72°, Angle 3 is 72°, or D.

Answer 2

Answer is C (108).

All 4 angles combined are always 360 degrees. In this case if you add 2 angles combined thehy are always 180 degrees.

If we know angle 1 is 72 than angle 3 is 180-72
And 180-72 =108
