TB can also infect other parts of the body, including the kidneys, spine and brain. People can have TB and not be sick, this is called latent TB.
Then the hypotenuse of each of those triangles is x*sqrt(2). But that hypotenuse is one of the sides of the octagon, so each side of the octagon has length x*sqrt(2) You are calling the diameter of the octagon the distance from side to side; this is the same as the length of the side of the original square.
To find the exterior angle of a regular octagon, we use the fact that the exterior angle forms a linear pair with the interior angle, so in general it is given by the formula 180-interior angle. See Exterior Angles of a Polygon.
