6. Tyree planned to build a ramp from his window to the sidewalk so he could skateboard right out his window on his way to school. His window is 5 feet off the ground and the sidewalk is 20 feet from his house. How long will Tyree's ramp need to be to make it from his window to the sidewalk?​

Answer :

The length of the ramp Tyree will need to make from window to the sidewalk is 5√17 feet .

In the question ,

it is given that ,

height of the window is = 5 feet ,

distance of sidewalk from the Tyree's house is = 20 feet ,

We know that the angle between the wall and the floor is 90° ,

So , the system is making a right triangle  ,

let the length of the ramp be = "x" ,

So, According to Pythagoras Theorem ,

we get ,

x² = 5² + 20²

x² = 25 + 400

x² = 425

x = √425

x = 5√17 feet .

Therefore , the length of the ramp is 5√17 feet .
