Answer the picture please and thank you!! :))

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

false

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
