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?
Yes! OHHH i got it!
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.
Didnt think about it that way lol
Im not that great at geometry, so thats, like, theonly way I know how to look at it xD
