Read each question carefully and show all your work. Round your answers to two decimal places where necessary.
1. The angle of depression is formed by the horizontal line of sight and the line of sight to an object that is:
Above the horizontal
Below the horizontal
At the same level as the horizontal
Perpendicular to the horizontal
2. If the angle of depression from a bird to a worm on the ground is 30 degrees, what is the angle of elevation from the worm to the bird?
30 degrees
60 degrees
