Non proportional I think. Wait for someone else to answer
59 degrees t and s are the same because they share an arch and angle is half of the circle length 118/2=59
For this case, the first thing we must do is define variables:
x: number of pillowcases
y: number of sheets
We now write the system of equations:
2x + 5y = 40
x = 2y
Solving the system we have:
x = 8.9
y = 4.4
Answer:
The maximum number of pillowcases she could have purchased is:
x = 8 (spent less than $ 40)
Vertical angle are always congruent
