I don't have anyone to ask for help with my geometry homework, so I was hoping someone could tell me how to solve and/or the answers to these problems? (One is angle of elevation, one is angle of depression.)
1.) Anna is watching a space shuttle launch 6 miles from Cape Canaveral in Florida. When the angle of elevation from her viewpoint to the shuttle is 80 degrees, how high is the shuttle if it is going straight up?
2.) Isaac is looking through binoculars on a whale watching trip when he notices a sea otter in the distance. If he is 20 feet above sea level in the boat, and the angle of depression is 30 degrees, how far away from the boat is the otter (to the nearest foot)?
