A 30-ft ladder is placed against a building. The bottom of the ladder is 18 feet from the base of a building. How tall is the building?

24 ft tall

Step-by-step explanation:

a^2+b^2+c^2

18^2+b^2=30^2 where b in this case is the height of the building

it could be 1,3 and more others to create a cylinder.

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
