Question

g

Answer 1

Since we know that the exterior angle is equal to the sum of opposite interior angles, we can apply it in the problem.
Here, the exterior angle is angle XYZ=137 and the opposite interior angles are angle W and angle X.
We have, angle X=59 and we know that angle XYZ= angles X+W
So, 137=59+W
or W=137=59
or W=78(Answer)

Answer 2

Hence, the correct option is C. 78
