Geometry - Right Triangle Trig

Answer the questions below using the dynamic image.

Question #1

What is the angle of elevation to the nearest whole degree from Barbara's position to the top of the Eiffel Tower?

[math]50^o[/math] [math]40^o[/math] [math]30^o[/math] [math]60^o[/math]

Question #2

What is the angle of depression to the nearest whole degree from the top of the Eiffel Tower to Barbara's position?

[math]70^o[/math] [math]40^o[/math] [math]60^o[/math] [math]50^o[/math]

Question #3

What is Barbara's distance from the Eiffel Tower to the nearest tenth?

28.6 30.0 31.1 29.9

Question #4

If Barbara decides to stand closer to the Eiffel tower how does her new position change the angle of elevation? How does it change the angle of depression? Use the blue point at Barbara's position to move her closer. Calculate the new angle of depression/elevation and compare them to your answers in question 1 and 2.

Question #5

If Barbara decides to stand farther from the Eiffel tower how does her new position change the angle of elevation? How does it change the angle of depression? Use the blue point at Barbara's position to move her farther from her original position. Calculate the new angle of depression/elevation and compare them to your answers in question 1 and 2.
