Answer:
Angle 2 & 4 = 72
Explanation:
Angle 7 is corresponding to angles 3.
So, since we know angle 7 = 108, then angle 3 = 108.
Angle 3 is supplementary to angle 2, which means they add up to 180º.
So if angle 3 = 108.
Then:
Angle 2 + 108 = 180
Angle 2 = 72º.
Angle 2 & angle 4 are vertical angles, so they have the same measure. Therefore,. If angle 2 is 72º, then angle 4 has to also be 72º.
Hope this helps! Have a great day!
