Aramp is being used to unload the back of a truck. if the ramp is 5 feet long, and the back of the truck is 3 feet tall, how far will the end of the ramp be from the back of the truck? 2 ft 8 ft 5.8 ft 4 ft !

Use the Pythagoras Theorem:-

5^2 = x^2 + 3^2

x^2 = 5^2 - 3^2 = 16

x = sqrt 16 =4 feet Answer

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
