16. tyler ate 42 grapes from a bowl.
there were 90 grapes in the bowl
to begin with. what percent of
the grapes did tyler eat?

90-42=58

58/90 = 0.644444444

So the percent ROUNDED is 64 1/4%

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°
