Determine whether a tangent line to circle O is shown in the diagram, for AB = 7.75, OB = 4, and AO = 8.75. Explain your reasoning. (The figure is not drawn to scale.)

Well, if that line is tangent to the circle, then the triangle, in this case, would havetobe a right triangle, correct?

Mhm. Well if it were a right triangle, then that would mean that the pythagorean theorem would be valid. So if it is a right triangle, then \[8.75=\sqrt{4^{2}+7.75^{2}}\] So thats up to you to check

i got that to equal 8.72?

Right, so that means this isnt a right triangle because we didnt find it to equal 8.75. So it is not tangent then.
