Best ResponseYou've already chosen the best response.3Well, if that line is tangent to the circle, then the triangle, in this case, would havetobe a right triangle, correct?

Best ResponseYou've already chosen the best response.3Mhm. 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

Best ResponseYou've already chosen the best response.3Right, so that means this isnt a right triangle because we didnt find it to equal 8.75. So it is not tangent then.
