Ashoe keeper marks his goods at 40% above cost (the price he pays for the goods) and then offers a 25% discount. if a jacket costs the shopkeeper $200, at what price is it sold? a. $180b. $200c. $210d. $230

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
