Angles of Elevation & Depression

Creepy Eyes Activity

Back to angles of elevation and depression.

Unbeknownst to Jose, a group of friendly, although creepy, aliens arrived on his lawn and are watching him from the shadows. Known as Teeki Weekis, these aliens do not have any body parts except eyes and eyebrows, and they came to Jose’s house simply to collect data on humans by observing Jose. The Teeki Weekis then plan on going back to their home, planet Teek, with this data. However, the Teeki Weekis do NOT want to be seen by Jose. At what angles of elevation and depression would Jose see the Teeke Weekis?
