Question

B To A is 6,400 . The radius is 4,000. segment AB is tangent to the circle. What is the approximate distance from B to c?

Answer 1

@JayDS

Answer 2

use the relation

AB^2 = BC * BO

Answer 3

I KNOW TYPING ERROR IT IS 'CAN ALSO'

Answer 4

to me, I prefer Pythagorean. AB^2 + AO^2 = (BC + CO)^2 , directly get BC

Answer 5

10,000?

Answer 6

@Loser66 your way seems easier to me. but what is AO?

Answer 7

AO and CO is radius. from the right hand side: (BC + CO)^2 = BC^2 + 2 BC*CO + CO^2
so, we can cancel CO^2 with AO ^2 from the left hand side
