900 feet

Answer 1

Answer:

1035.33 feet

Step-by-step explanation:

Given :

⇒ Distance between the observer and building = 900 feet

⇒ Angle of elevation = 49°

============================================================

Solving :

⇒ tan 49° = h / 900

⇒ h = 900 × 1.1503684072

⇒ h = 1035.33 feet
