Wang owes the bank $8500. to repay the debt, he paid a fixed amount to the bank each month. after 12 months, his remaining debt was $6460. how much did wong yang pay each month? how long did it take yang wong to pay back his entire debt?

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°
