Right Triangles
They are a special type of triangle where one of its internal angles is 90°. The basic trigonometric equations stand in this type of triangles. If x is the adjacent leg of a given angle , and y is the opposite leg to the same angle, then :
We can solve for x to get
Corey estimates the height of the tree to be 80 feet. This means we know y=80 and . Let's find the horizontal distance at which Corey is looking at the bald eagle:
Now Corey moves back to watch the very same tree at an elevation angle of 41°. The tree has the same height, so
Now we can know the distance Corey walked back by subtracting both distances
