Please help! I have no idea how to this and I have a quiz over it in two days!

put the equation on the calculator but instead of the beginning put y  

Step-by-step explanation:

hope this helps

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°
