Angle c (36 degree) is equal to angle a
Angle a=36 degree
a+b=180
b=180-36
b=144 degree
Angle b=144 degree
A = 7x, c = 4x, s = 3x
a = s+52
7x = 3x+52
4x = 52
x = 13
c = 4x = 52
Caroline gets 52.

Answer:
Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54
Step-by-step explanation:
Ms. Wang is shopping for a new refrigerator. Brand A costs $569 and uses 635 kilowatt-hours per year. Brand B costs $647 and uses 582 kilowatt-hours per year.
Let's assume he buys brand B, so he already has a loss over the price of the commodity that is , loss = 647 - 569 =$78
Cost of electricity = $0.18
Now in the case of electricity,
spending on Brand A = 635
0.18 = $114.3
spending on Brand B = 582
0.18 = $104.76
Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54
