This is a right angled triangle. Let be the angle of elevation.

Let the adjacent side of the triangle be x for the angle

Let the opposite side of the triangle by y for the angle

Thus,

Since, the height of the tree is 80 feet,

To find the value of x, let us substitute and

Since, Corey moves back a few steps to gain a better view of the bird, the angle of elevation is 41°

Now, we shall find the x for and

To find how many feet Corey step back is to subtract the value of two adjacent sides, thus,

Thus, **Corey stepped back 59.71 feet to get a better view of the bird.**
