Answer:
A)
B)
Step-by-step explanation:
a) <u><em>According to Outside Angles theorem:</em></u>
=> m∠VYW =
Where mVX = 79, VW = 173
=> m∠VYW = (173-79)/2
=> m<VYW = 94/2
=> m∠VYW = 47 degrees
b) <u><em>According to Angles of Intersecting Chords Theorem:</em></u>
=> m∠VZW =
Where m∠VZW = 64, VW = 51
=> 64 = 1/2(51+XY)
Multiplying both sides by 2
=> 64*2 = 51+XY
=> 128 = 51+XY
=> XY = 128-51
=> XY = 77 degrees
