Sagot :
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
