Your friend asks you to help her babysit and will pay you 3 pennies for the first job. You agree to help if she triples your payment for each job completed. After 2 jobs, you will receive 9 pennies, and after 3 babysitting jobs, you will receive 27 pennies. Complete and solve the equation that finds the number of pennies she will pay you after the 9th babysitting job.

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°
