Question

Help me find part A and B

Answer 1

Explanation:

From the given question,

a). m∠WAX = 60°

If m(arc WX) = 100°

Then by theorem,

Angle formed between the chords in a circle, measures the half of the sum of intercepted arcs.

m(∠WAX) =
`(1)/(2)(\text{arc WX + arcYZ})`

60° =
`(1)/(2)(100+\text{arcYZ})`

120 = 100 + arc YZ

120 - 100 = arc YZ

m(arc YZ) = 20°

b). m(arc WX + arc YZ) = 2(60°)

m(arc WX + arc YZ) = 120°
