Answer:
height of the tower = 2358.3 feet
Step-by-step explanation:
To solve this question, we can use the tangent relation of the angle of elevation, where the opposite side of the angle is the height of the tower minus six feet and the adjacent side of the angle is the distance from David to the tower. So, we have that:
tangent(78) = (height - 6)/500
4.7046 = (height - 6) / 500
height - 6 = 2352.3
height = 2358.3 feet
