Ginger is sitting in an observation post that has been built in a tree. She looks down on the Professor with an angle of depression of 50degrees. What is the angle of elevation from the Professor to Ginger?_______degrees

Respuesta :

The situation is represented by the next right triangle:

Since the sum of all interior angles adds up to 180°:

50+x +90=180

Solve for x (angle of elevation from the professor to ginger)

x= 180-90-50

x= 40°
