On Monday , Brian contes 28 ducks and Cathy counter 15 ducks. On Tuesday, they counted 37 ducks altogether .How many more ducks did they count on Monday and Tuesday

6 more ducks

Step-by-step explanation:

1. add 28 and 15

2. Subtract thirty seven from that value

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°
