Question

Brad is standing on a hill which place is him at the same height as a nearby flag pole the flag pole is 15 feet high and Brad is 20 feet high horizontally from the top of the pole brad can see the bottom of the flag pole what is the length in feet of brads line of sight to the base of the flag pole

Answer 1

The length in feet of Brad's line of sight to the base of the flag pole as required in the task content is; 25 ft².

Pythagoras theorem

It follows from the task content that the length in feet of Brad's line of sight to the base of the flag pole is to be determined.

Given;

The flag pole in discuss is said to be 15 feet high.

Also, Brad is at the same height as the pole and is at a horizontal distance of 20 feet from the top of the pole.

Therefore, the line of sight alongside the two other dimensions above form a right triangle where, the hypothenuse is; the line of sight.

Therefore, since hyp² = opp² + adj²

hyp² = 15² + 20²

hyp² = 225 + 400

hyp² = 625

hyp = 25.

Therefore, the length of the line of sight is; 25 feet.
