(3 points) If you are standing 30 feet away from the base of a 100-foot-tall tree, then how much do you have to tilt your gaze to see the top of the tree (i.e., what is its angle of elevation), to the nearest degree? Be sure to sketch a picture.

Step 1
The angle of elevation θ is at your eye, between the horizontal line and the line of sight to the treetop. Show more…

The height of the tree is 82.4 feet tall. The tree casts a shadow 30 feet long. What is the angle of elevation created from the tip of the shadow to the top of the tree? If needed, round to the nearest thousandth. (HINT: Draw a picture)

To find the height of a tree, a person walks to a point 30 feet from the base of the tree. The measure of the angle from the ground to the top of the tree is 57°. Assume the tree makes a right angle with the ground. How many feet tall is the tree? Round your answer to the nearest integer. To have a chance for partial credit, enter as much work as you can below. (Your calculator should be in degree mode unless you change the angle to radian measure.) The tree is approximately __________ feet tall.

A 30-foot tall tree casts a shadow 10 feet long. What is the angle of elevation θ of the sun (or the angle of elevation of the top of the tree)? Give your answer in degrees, rounded to one decimal place.
