Last year, your store had total sales of $190,000. because of a downturn in the economy, you expect sales to decrease by 3% this year. what are your planned sales for next year? a) $184,300 b) $187,000 c) $190,000 d) $195,700

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°
