O is the center of the circle above.

Is this an example of the 3 - 4 - 5 rule? Is that why Chris didn't necessarily have to show how to calculate it to get 5 (i'm guessing via the Pythagorean Theorem) because you can look at it and automatically recognize it's a 3 - 4 - 5 Rule and no calculation is needed?

Instead of finding out the value of x, can we just think : " Hey the radius is 5 and X is less than 5 because its end point is not on the circle, and therefore it must be less than the value of the radius" ?
Thanks
