Elodia [21]

Answer:

4 hours

Step-by-step explanation:

In 6 hours, J paints 1 room

So, in 1 hour, J paints 1/6 th of the room

Using similar logic, in 1 hour, T paints 1/12 th of the room.

Working together in one hour, they paint (1/6+1/12) th =1/4 of the room.

1/4 of the room is painted in 1 hour

So, 1 room is painted in 1 1/4=4 hours

From where Kiana is standing, she must look up at a 50° angle to see the top of a building. If she backs up 50 feet, she will ne

Morgarella [4.7K]

For this case, what we must do is solve the following system of equations:
tan (50) = h / x
tan (40) = h / (x + 50)
Solving the system we have:
(x + 50) * tan (40) = h
(x) * tan (50) = h
Matching:
(x + 50) * tan (40) = (x) * tan (50)
Rewriting:
x (tan (50) - tan (40)) = 50 * tan (40)
x = 50 * tan (40) / (tan (50) - tan (40))
x = 118.9692621
Substituting:
h = (x) * tan (50)
h = (118.9692621) * tan (50)
h = 141.7820455
Answer:
The height of the building is:
h = 141.7820455 ft
