Asked by Kelley

a blimp, suspended in the air at a height of 500 feet, lies directly over a line from Soldier Field to the Adler Planetarium on Lake Michigan. if the angle of depression from the blimp to the stadium in 32 degrees and from the blimp to the planeterium is 23 degrees, find the distance between soldier field and the Adler Planetarium
Answered by Steve
as always, draw a diagram. Then it should be clear that the distance is

500 cot32° + 500 cot23°
