The angle of elevation to the top of the door is 47 degrees, and the angle of elevation to the ceiling above the door is 62 degrees. If the ceiling is 10 feet off the floor, what is the height of the door?

Answer :

Final answer:

The height of the door is approximately 10.724 feet.

Explanation:

To determine the height of the door, we can use trigonometry and the given angles of elevation. Let's consider the triangle formed by the floor, the door, and the line of sight to the top of the door.

Since we know the angle of elevation to the door is 47 degrees, we can use the tangent function to calculate the height of the door. Let's denote the height of the door as 'x'.

Tan(47) = x/10ft

x = 10ft * tan(47)

x ≈ 10ft * 1.0724

x ≈ 10.724ft

Therefore, the height of the door is approximately 10.724 feet.
