Answer: B) 133

=======================================================

Step-by-step explanation:

Use the remote interior angle theorem. This says to add the interior angles shown, and you'll get the exterior angle that is not adjacent to those interior angles.

68+65 = 133

So angle B is 133 degrees

------------------

A longer alternative is to let C be the missing interior angle of the triangle. Then we can find that

68+65+C = 180

C+133 = 180

C = 180-133

C = 47

Angle C is adjacent to the exterior angle B, meaning

B+C = 180

B+47 = 180

B = 180-47

B = 133
