Question

inscribed angles help?

Answer 1

AB is tangent to O. If AO=12 and BC= 25 what is AB?
35
37
50
47

Answer 2

so this is whats given.
can you find CO?

Answer 3

no im confused lol

Answer 4

so what is OC?

Answer 5

its the radius of the circle, right?
and AO is also a radius.
and all radius of the same circle have equal lengths.
So what is the length of OC?

Answer 6

@jessicawade? What are you confused about. @nikato just demonstrated that the triangle is a right triangle. Therefore, apply Pythagorean's Theorem.

Answer 7

12

Answer 8

CO is 12 because AO is 12

Answer 9

Yes.
So BO=25+12=37
Now to find AB, use the pythagoereom theorem.
Let AB=x
So
x^2 +12^2 =37^2
And then solve for x
