Mr. Cooper ask his students whether they prefer to go to the aquarium or the planetarium for a field trip. The table shows the result

table says:
response | percent

aquarium | 50

planetarium | 25

suppose the rest of the class had no preference what is the ratio of students who have no preference to the students who prefer to go to the aquarium

1:5 1:4 1:3 1:2

1/2

Step-by-step explanation:

It is 1/2 because 50 percent is the aquarium and the other 50 percent is unknown.

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°
