Ответ:
404.89 feet
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of elevation of the bird (B), the opposite side (x) is the length of the bird above the ground, and the adjacent side is the distance between the school (S) and the observer (O).
Replacing with the values given:
Tan 39 = x/ 50 0
Solving for x
tan39 (500) =x
x= 404.89 feet
