to approximate the length of a marsh a surveyor walks 245 meters from point A to point B then turns 90 degrees in walks 215 Meters to point C approximate the length of AC the marsh

We have the next information about the problem
AB= 245 m
the angle in B =90°
BC=215 m
Because we have an angle of 90° we can affirme we have a right triangle and we can use the Phytogras Theorem
