Question

If OB = 10 and AR = 6, then OR =

Answer 1

examples?

Answer 2

we can prove that AR = AB by pointing out these two triangles:

Answer 3

OA is also a radius of the circle so OA = OB = 10

Answer 4

because OAR and OBR have the same leg OR and hypotenuse (OA and OB then OAR and OBR are equal and thus AR = AB

Answer 5

now, just look at triangle OBR

you have a right triangle w/ hypotenuse = 10, leg = 6, use the pythagorean theorem to find the other leg OR
