I want to build a ramp that is 3 feet tall and a 4 feet long base but I don't know how long the top of the ramp needs to be.
To find how long the ramp needs to be you need to use Pythagorean Theorem
How do I use Pythagorean Theorem
You have to use the equation a squared plus b squared equals c squared. You a squared is 3 and your b squared is 4. Now you have to find out c squared.
Next you have to find out what each number squared is. 3 squared is 9, and 4 squared is 16.
The new equation is 9+16=c squared. Next add 9 and 16 together. Now the equation is 25=c squared.
Lastly you have to find the square root of 25 because c is squared so you have to undo the other side.
The square root of 25 is 5!
