REQUIRED Amelia stood on a ladder. Her eyes were 9 feet above the ground. On the ground, a lizard was a horizontal distance of 10 feet away from Amelia. What is the angle of depression from Amelia's eyes to the lizard? Round answer to the nearest degree. Type a response
Added by Marina A.
Step 1
In this case, it is the angle formed by Amelia's line of sight to the lizard. We can use the tangent of the angle of depression, which is the ratio of the opposite side (the height difference) to the adjacent side (the horizontal distance). So, the tangent of Show more…

The angle of depression from an observer in an apartment complex to a gargoyle on the building next door is $55^{\circ}$. From a point five stories below the original observer, the angle of inclination to the gargoyle is $20^{\circ}$. Find the distance from each observer to the gargoyle and the distance from the gargoyle to the apartment complex. Round your answers to the nearest foot. (Use the rule of thumb that one story of a building is 9 feet.)
