"Hi, I have looked for something that specifically looks at angles of elevation and depression. Unable to find these as a separate of questions. Do you have a specific of questions relating to this?
Many thanks.
[Transum: Thanks for your comment John. You can find exam-style questions on the Angles of Elevation and Depression page.]"
