I'm fine with angle of elevation problem, but angle of depression problems are tricky for me. Is this right?
From a balloon 835 m high, a command post is seen with an angle of depression of 7 degrees. How far is it from the point on the ground directly below the balloon to the command post?
I drew a picture and thought that I would say
Tan of 83= x/835
Then i got 6800.53
Is that right?
