An observer (o) is located 900 feet from a building (b). the observer notices a helicopter (h) flying at a 49° angle of elevation from his line of sight. how high is the helicopter flying over the building? you must show all work and calculations to receive full credit.
a right triangle is shown with one leg measuring 900 and another leg measuring h, with an angle across from it measuring 49 degrees.

answer:

the answer to your question is h = 932 ft

step-by-step explanation:

data

observer = point 0

building = 900 ft = adjacent side

angle = 49°

height = h

process

1.- find a trigonometric function that relates the opposite side and the adjacent side.

this function is tangent

          tan ф =

          tan ф =

solve for h

          h = 900 tan (46)

          h = 900 x 1.036

          h = 931.98 ft

yes

step-by-step explanation:

yes
