Best ResponseYou've already chosen the best response.2If segment AB is tangent to circle O at point B, what does that say about segments AB and OB? Yes, it is a right triangle. Which means what?

Best ResponseYou've already chosen the best response.2Well, you're given two sides of the right triangle and need to find the length of the third side. What rule do we use for this situation?

Best ResponseYou've already chosen the best response.2Actually, you have to find the correct "a", "b" and "c" when using the pythagorean theorem.

Best ResponseYou've already chosen the best response.2"a" and "b" are always the "legs" of the right triangle. "c" is always the hypotenuse. Sometimes, they give you "a" and "c", but not "b".

Best ResponseYou've already chosen the best response.2I thought you already learned about right triangles. I'm going to say it again. Sometimes, you're given "c" instead of "b", which means, if you have something like a = 3 c = 5 then you have to solve for b: a^2 + b^2 = c^2 3^2 + b^2 = 5^2 b^2 = 5^2  3^2 b^2 = 25  9 b^2 = 16 b = 4

Best ResponseYou've already chosen the best response.2In this case, a = r b = 10 c = 11.7 So \(a^2 + b^2 = c^2\) becomes: \(r^2 + 10^2 = 11.7^2\) You subtract 10^2 from both sides: \(r^2 = 11.7^2  10^2\) Then square root both sides to get \(r = \sqrt{11.7^2  10^2} \)

Best ResponseYou've already chosen the best response.2You'll have to finish simplifying \(r\) on your own. I'm not going to do that for you. Just let me know what you get. I'll say whether or not it's right or wrong.
