Answer:
Value of X = 20
Angle of Measurement #1 = 95
Angle of Measurement #2 = 85
Enjoy!
Explanation:
Since the whole thing is over a straight line or 180 degrees, you should make the equation 180 = 7x + 40 since you'd add all the numbers together, solving the equation from here is what you'd need to do (subtract 40 from both sides and divide by 7 after to get x). but here are the answers to both since the angle measurement doesn't specify whether 1 is for right or left.
