<span>Let's divide this problem into three shape and next we will compute the area for each shape:</span>
(1) First triangle
(2) Rectangle
(3) Second Triangle
(1) The best known and simplest formula is:
<span>where b</span> is the length of the base of the triangle, and h is the height or altitude of the triangle. Using trigonometry the base is given by:
Therefore:

Answer:
The ladder has to be 65 feet long to the nearest foot.
Step-by-step explanation:
The height of the chimney from the ground is the sum of the height of the wall and the height of the chimney.
Therefore, the height of the chimney from the ground = (30 + 33) = 63 feet.
Now, the ladder makes a right triangle with the ground and the chimney and the ladder makes an angle of 75.5° with the ground.
Therefore, using trigonometry we can write,
⇒ The length of the ladder = 65 feet.
Hence, the ladder has to be 65 feet long to the nearest foot. (Answer)
