Firefighters just arrived at the Farquand building with a rescue truck. Mr. Farquand is stuck on a window ledge 44 feet directly above the top of the truck. The base of the ladder is a horizontal distance of 33 feet away from the building. Using the Pythagorean Theorem, determine how long the ladder must extend to reach Mr. Farquand.

The length of the ladder must be 5ft

Step-by-step explanation:

Given

--- H

---- B

Required

Determine the length of the ladder (L)

It'll be assumed that the ladder is on the truck

So, the length of the ladder forms the hypothenuse

Using Pythagoras:

Substitute values for H and B

Take square root of both sides

Hence:

The length of the ladder must be 5ft

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
