Answer:
71.6056
Step-by-step explanation:
c² = a² + b² - 2abcosC°
29² = 30² + 15² - 2(30)(15)cosC°
841 = 900 + 225 - 900cosC°
-59 = 225 - 900cosC°
-284 = -900cosC°
71/225 = cosC°
cos⁻¹(71/225) = C°
C° = 71.6056

Correct option is A. Money saved is ′ $6 ′ .
Given
Regular price of the refrigerator = $600
i) Buying the refrigerator at 20 percent off regular price
Final Discount in this case = 20% (Regular price of the refrigerator)
= 20 / 100 × 600
= $120
ii) Buying it on sale at 10 percent off regular price and an additional 10 percent off sale price
Discount for the sale = 10% (Regular price of the refrigerator)
= 10/100 × $600
= $60
Sale price of the refrigerator = Regular price of the refrigerator − Discount for sale
= $600 − $60
= $540
Final Discount in this case = 10% (Sale price of the refrigerator)
= 10/100 × $540
= $54
Money saved if we buy as (case−i) = (Final Discount in (case.i)) − (Final Discount in (case.ii))
= $60 − $54
= $6
Therefore, Money saved is ′ $6 ′ .
