apparently i am missing something :/

cwrw238 · Answer

If AB is a tangent triangle ABO will be right angled at B

see if the lengths of the lines fit the pythagoras theorem

cwrw238 · Answer

A line drawn from the centre of a circle to the point of contact of a tangent is at 90 degrees to the tangent.

@cwrw238 like what i attached

There are two possibilities though. Either

a) That is not a tangent line for reasons you correctly pointed out.

b) The measurements done weren't accurate. (It is a tangent line but one side is clearly off)

But I think it's a) so yeah, what's the issue ?
