Two public works employees are installing a wheelchair ramp near the steps of a public library. the main door to the library is 6 feet off the ground. assuming the horizontal distance of the ramp is 24.8, what is the length of the ramp? round to the nearest tenth of a foot.

Two public works employees are installing a wheelchair ramp near the steps of a public library. The length of the ramp is 25.51 feet.

Solution:

Consider the diagram attached below.

Let AB be ground. C be the position of main door.

As horizontal distance of the ramp = 24.8 feet

So AB = 24.8 feet

Main door of the library is 6 feet off the ground.

So CB = 6 feet

Need to calculate length of the ramp that is AC.

By Pythagoras theorem, square of one side of a right triangle is equal to sum of square of other two sides.

On applying Pythagoras theorem in right triangle ABC, we get

On substituting value of AB and BC,

= 25.51 feet

Hence length of the ramp is 25.51 feet.

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

combine all like terms then its just a 2 step equation
