∠XWY is an inscribed angle because it has a vertex on the circle. This means that m∠XWY is half of the arc it intercepts, which is XY. We can model the situation using an equation:
m∠XWY = mXY / 2
37° = mXY / 2
mXY = 74°
All arcs in a circle add up to 360°. Because of this, we can say:
I got 27.5 for the mean mean: you add up all the #'s and divide them my their quantity( in other words by how many numbers there are) In your case you have 8 numbers, you add them and divide them by 8!
