A ladder that is 20 ft. Long is leaning against the side of a building. If the angle formed between the ladder and the ground is
75, how far is the bottom of the ladder from the base of the building?
1 answer:
Answer:
The ladder from the base of the building is 5.18 ft (Approx)
Step-by-step explanation:
As given
A ladder that is 20 ft. Long is leaning against the side of a building.
If the angle formed between the ladder and the ground is 75.
Now using the trignometric property .

As shown in the figure.
Base = CB
Hypotenuse = AC = 20 ft.
Put in the trignometric identity .



Put in the above


CB = 0.259 × 20
CB = 5.18 ft (Approx)
Therefore the ladder from the base of the building is 5.18 ft (Approx) .
