Noah wants to clean his second story windows and plans to buy a ladder that will reach at least

22

feet high. If he leans the ladder against the house so that the base of the ladder makes a

51.5

∘

angle with the ground, how long of a ladder should he buy? Please round to one decimal place

Noah should buy a ladder of length greater than 28.1 ft to reach at least 22 feet height.

Step-by-step explanation:

Given:

Noah has to reach at least 22 ft height.

Angle made by the base of ladder with the ground = 51.5°

To find the length of the ladder.

Solution:

On drawing the situation, we get a right triangle. The hypotenuse of the triangle represents the length of the ladder.

In triangle ABC.

∠C = 51.5°

AB = 22 ft

Applying trigonometric ratio to find AC (length of the ladder).

Plugging in values.

Multiplying AC both sides.

Dividing both sides by

Thus, Noah should buy a ladder of length greater than 28.1 ft to reach at least 22 feet height.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
