Determine wether the equation is an identity or not an identity

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

if you would like with a question it is easy to get an answer by including some or multi choice options

step-by-step explanation:

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
