Angle of Elevation & Depression Day 2 March 29, 2018
Objective : Given a right triangle, students will be able to write and use trigonometric ratios to solve in applied problems involving angles of elevation and angles of depression.
Angle of Elevation and Depression Day 2 A dog, who is 8 meters from the base of a tree, spots a squirrel in the tree at an angle of elevation of 40°. What is the directline distance between the dog and the squirrel?

You are standing on top of a building, looking at a park in the distance. The angle of depression is 53∘. If the building you are standing on is 100 feet tall, how far away is the park? Does your height matter?

If we ignore the height of the person, we solve the following triangle:
If we take into account the height of the person, this will change the value of the adjacent side. For example, if the person is 5 feet tall, we have a different triangle:
A 70 foot building casts an 50 foot shadow. What is the angle that the sun hits the building?Explore3
Explore4What is the angle of elevation if you stand 850 feet away from a cliff that is 400 feet high and look at the top?
