Francesca is looking at an airplane. she measures the angle at which she is looking up and finds it to be 55 degrees. if the airplane is traveling at an altitude of 3 feet, about how far is the airplane from francesca?
a. 21,006 feet
b. 36,623 feet
c. 45,043 feet
d. 53,303 feet

B is the correct answer Hope it 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°
