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

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

126 maybe. sorry
