Which equation is correct regarding the measure of ∠mnp?
m∠mnp = (x – y)
m∠mnp = (x + y)
m∠mnp = (z + y)
m∠mnp = (z – y)

The correct answer to this question is choice " m∠mnp = (x – y)"

far arc = x
near arc = y

angle mnp = (far arc - near arc) / 2
angle mnp = (x - y) / 2

from the given choices, it is assumed that there is a denominator of 2 that divides the whole expression.

Assuming this is a question on a test just name a restaurant by your house and the state you live in, its not too difficult : )
