## OpenSessame Group Title 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.) one year ago one year ago

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

3. OpenSessame Group Title

Yes! OHHH i got it!

4. Psymon Group Title

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

5. OpenSessame Group Title

i got that to equal 8.72?

6. Psymon Group Title

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

7. OpenSessame Group Title

Thanks man!

8. Psymon Group Title

Yep :3

9. OpenSessame Group Title

Didnt think about it that way lol

10. Psymon Group Title

Im not that great at geometry, so thats, like, theonly way I know how to look at it xD
