1) Bill is paying more per lesson.

2)Bill is paying 50 cents more per lesson.

Step-by-step explanation:

Crista: 126/28=$4.5 per lesson

Bill: 30/6=$5 per lesson

5-4.4=0.5

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°
