11. 57% = 0.57
12. retail price = c + (0.57c)
13. retail price = 45 + (0.57 x 45)
retail price = 45 + 25.65
retail price = $70.65
14. 57% was added to the original price of the chain which is $25.65
Answer:
letter b
Step-by-step explanation:
Answer:
55.2° ≤ c ≤ 55.8°
Step-by-step explanation:
We know a + b + c = 180
Let's take the smallest value of a and b and find largest value of c:
51.3 + 72.9 + c = 180
c = 55.8
Now,
Let's take the largest value of a and b and find smallest value of c:
51.5 + 73.3 + c = 180
c = 55.2
Thus, we can say, range of c is:
55.2° ≤ c ≤ 55.8°
