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)

A triangle has three sides. A ratio is a comparison of two things. We pick two different sides of the triangle to compare (because there is not much point in comparing one thing to itself). How many ways are there to do this? The first choice has 3 options, and the second has 2, so we have a total of

possibilities.
