Answer:

D

Step-by-step explanation:

given VS is a diameter of the circle. then VS is a straight angle of 180°

The 3 angles below VS , sum to 180° , that is

x + 46° + 96° = 180° ( simplify left side )

x + 142° = 180° ( subtract 142° from both sides )

x = 38

The 3 angles above VS , sum to 180° , that is

22° + ∠ WQR + x° = 180° ( substitute x = 38 )

22° + ∠ WQR + 38° = 180°

∠ WQR + 60° = 180° ( subtract 60° from both sides )

∠ WQR = 120°
