Abird watcher spied a woodpecker. the bird watcher is 40 yards lower than the woodpecker. the distance from the bird watcher to the woodpecker is 175 yards. what is the angle of elevation? a. 12.9° b. 13.2° c. 76.8° d. 77.1°

Option: b is the correct answer.

                     b.   13.2°

This problem can be modeled with the help of a right angled triangle and let the angle of elevation be θ.

Also, the side opposite to angle θ is: 40 yards.

and the hypotenuse of the right triangle is: 175 yards.

Hence, In right angled triangle i.e. ΔABC is:

i.e.

i.e.

The angle of elevation is: 13.2°

answer: 8
