if 12 marbles cost $250 how much it will cost if there is 155 marbles? please to show working out.

if 12 marbles = $250

155=?

so we use cross product

which is 155*250$/12= 3,229.1666666667

Step-by-step explanation:

so the answer is 3,229.16 in short

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°
