Using Pythagoras theorem we have

a² = b² + c²

where

a is the hypotenuse

We have

Find the square root of both sides

That's

We have the final answer as

Hope this helps you

h who knows

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
