Question 1 of 3

A bird perched on a 25 m tall telephone pole watches a mouse on the ground 40 m away (horizontal distance). What is the angle of depression from the bird to the mouse?

Question 2 of 3

A student stands 50 meters from the base of a building and observes the top of the building at an angle of elevation of 32°. Find the height of the building to the nearest meter.

Question 3 of 3

A surveyor stands 50 m from the base of a cliff and measures the angle of elevation to the top as 62°. How tall is the cliff? (Round to the nearest meter.)

How this fits in

Angles of elevation and depression is one skill in the Trigonometry unit. Students read the unit lesson, then earn a bronze, silver, or gold medal on their last 10 answers. Medals never go down. A mastered unit comes back for review after 1, 3, 7, 16, and 35 days so it stays learned.
