Answer:

<4 is 102 and <1 and <3 are both 78

Step-by-step explanation:

<4: 102 because it is vertical to <2, and all vertical angles are congruent

<1: 78 angle 1 is adjacent to angle 2, meaning that they share a side. Because of this they are a linear pair, so they add up to 180. 180-102

<3:Using the vertical angles theorem, we can say that <1=<3 as they are vertical angles.

Answer:

1 = 78 degrees

3 = 102 degrees

4 = 78 degrees

Step-by-step explanation:

All of the angles are supplementary which means two of the angles add up to 180 degress

Angle 2 = 102

To find angle 1, just subtract 102 from 180

180 - 102 = 78

Angle 4: 180 - 78 = 102

Angle 3 = 180 - 120 = 78
