Question

If you place a 28-foot ladder against the top of a 22 foot building

Answer 1

Answer:

17.3 ft

Step-by-step explanation:

To find the second leg, use the following: √c² - a². Substitute c for 28, and a for 22.

b = √28² - 22² {Square 28 to get 784, and square 22 to get 484.}

b = √784 - 484 {Subtract 484 from 784 to get 300.}

b = √300 {Find the square root of 300.}

b = 17.32051 {Round to the nearest tenth.}

b = 17.3 ft.

The bottom of the ladder will be 17.3 ft from the bottom of the building.
