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 30,000 feet, about how far is the airplane from Francesca?

For the airplane problem

 

 sin 55 = (30000ft/distance)     Solve for distance =36,623.23 ft
