Two students had the following scores on five history tests. Student A: 82, 90, 87, 91, 97
Student B: 84, 91, 89, 95, 91
Which set of scores shows more variation? Use the MADs to justify your answer.

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°
