Answer:
B. 34º
Step-by-step explanation:
So we know that a straight line is equal to 180º and we already have to measure of angle 2. So to find the angle of measure 1, we just subtract 146 from 180.
180 - 146 = 34
So the measure of angle 1 is 34º.
Now, because of alternate exterior angles, we know that they would be the same. SO m∠7 = 34º
