Triangle x y z is shown. line z x is extended through point w to form exterior angle w x y.
which statement regarding the diagram is true?

m∠wxy = m∠yxz
m∠wxy < m∠yzx
m∠wxy + m∠yxz = 180°
m∠wxy + m∠xyz = 180

m∠WXY + m∠YXZ = 180°

the real answer is c just took the test

Step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
