Answer:
B; 94 degrees
Step-by-step explanation:
From the diagram, what we have is a cyclic quadrilateral
For a cyclic quadrilateral, opposite angles are supplementary
That means;
They add up to give 180 degrees
Mathematically;
angle D + angle B = 180
angle B = 180 - angle D
angle B = 180-86
angle B = 94 degrees
