Answer: 140 degrees
A straight line is 180 degrees. Since we know one of the angles in the line is 40, we just subtract 40 from 180. So, the measure of angle 1 plus the measure of angle 2 is 140 degrees.

Answer:
B. x = 53 degrees.
Step-by-step explanation:
The external angles of all polygons add up to 360 degrees, so:
x + 120 + 90+ 97 = 360
x = 360 - 90 - 120 - 97
x = 53 degrees.
