Answer:
(c) 13.2
Step-by-step explanation:
The sum of angles in a triangle is 180°, so angle C is ...
C = 180° -A -B
C = 180° -16° -49° = 115°
The measure of side c can be found from the Law of Sines:
c/sin(C) = a/sin(A)
c = a·sin(C)/sin(A) = 4·sin(115°)/sin(16°)
c ≈ 13.2
Answer:
$2.50 coupon is better as it gives a cheaper sale price.
Step-by-step explanation:
Price of good = $12
Sale price = price of good - coupon
Coupon 1 :

Coupon 2:
15% off
Sale price =. (100 - 15)% * 12
= 0.85 * 12
= $10.2
