Answer:

a = 57

b = 24

c = 39

d = 60

Explanation:

Theorem:

In a circle, inscribed angles that intercept congruent arcs are congruent.

<XWY and <YZX intercept arc XY; therefore they are congruent.

m<XWY = m<YZX

a = 57

<YWZ and <ZXY intercept arc ZY; therefore they are congruent.

m<YWZ = m<ZXY

b = 24

<XYW and <WZX intercept arc WX; therefore they are congruent.

m<XYW = m<WZX

c = 39

<ZYW and <YXZ intercept arc WZ; therefore they are congruent.

m<ZYW = m<YXZ

d = 60
