Aramp extends from the back of a truck bed to the ground. the back of the truck bed is 4 feet above the ground. the horizontal distance from the spot below the back of the truck bed to the bottom of the ramp is 3 feet. how long is the ramp?

5 feet.    

Step-by-step explanation:

Please find the attachment.

Let x be the length of ramp.

We have been given that a ramp extends from the back of a truck bed to the ground. The back of the truck bed is 4 feet above the ground. The horizontal distance from the spot below the back of the truck bed to the bottom of the ramp is 3 feet.

We can see from our attachment that ramp and the height of truck bed form a right triangle, so the length of ramp will be equal to hypotenuse of right triangle with two legs of 4 feet and 3 feet.

We will use Pythagorean theorem to solve for the length of ramp.

Upon taking square root of both sides of our equation we will get,

Since length of ramp can not be negative, therefore, length of ramp will be 5 feet.
