Answer:
B) 6
Step-by-step explanation:
The marked angles are an exterior angle and the corresponding two remote interior angles. The relation between these is that the exterior angle is equal to the sum of the remote interior angles. We can use this relation to find x.
65 = (3x +2) +(9 +6x)
65 = 9x +11 . . . . . . . . . collect terms
54 = 9x . . . . . . . . . . subtract 11
6 = x . . . . . . . . . . divide by 9
