Aladder is leaning against the very top of a building. the base of the ladder is 18 feet from the building and is leaning at a 60 degree angle. how tall is the building?

The height of the building is 18 feet .

Step-by-step explanation:

Given as :

The distance of the base of ladder from building = d = 18 feet

The ladder is leaning at the angle = Ф = 60°

Let the height of the building = h feet

Now, From figure

Tan angle =

Or,Tan Ф =

Or,Tan 60° =

Or, =

∴ h = 18 feet

So, The height of the building = h = 18 feet

Hence, The height of the building is 18 feet . Answer

47 is 0.5 of 94

Step-by-step explanation:

0.5 x 2 = 1

47 x 2 = 94
