6lb for $50.00 or 6.5 lb for $60.00?

Just find the unit price (price divided by amount)

6 lb for $50.00

50.00/6 = about $8.33 per lb

6.5 lb for $60.00

60.00/6.5 = about $9.23 per lb

6 lb for $50.00 would be the better deal

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°
