Answer:
B = 115
Step-by-step explanation:
Since A and B are supplementary, they add up to 180 degrees.
Thus, 65 + B = 180, and B = 115
The answer is the second one B ( s/6+ 95 3/9)
Since there was a ray drawn from A through C the exterior angle of angle C is angle 1. Any straight line should equal to 180 degrees.
