Question

I NEED HELP! THIS IS DUE TODAY! I don’t understand this and I don’t have any idea how to find the measure of the angles.

Answer 1

2= 43°

1=137°

3= 137°

Explanation:

.this is because 43° and 2 are vertically opposite angles.

.this is because 1 and 43° are on a straight line and angles on a straight line sum up to 180°.

.this is because 1 and 3 are vertically opposite angles.
