Sherman hopes to get at least a 90 average on his science tests. He has one more test before the end of the school year. His past test scores are 79, 94, 91, and 92. What is the lowest score Sherman can get on his final test and reach his goal?

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°
