Answer:

  B. 95

Step-by-step explanation:

If you take the figure at face value, the exterior angle is obtuse. The only answer choice that matches is choice B.

__

If you want to calculate the angle, you can make use of the fact that the exterior angle is equal to the sum of the opposite interior angles:

  8x +15 = (4x +5) +(3x +20)

  x = 10 . . . . . . . . . subtract 7x+15 and collect terms

Then the exterior angle is ...

  8·10 +15 = 95
