Circle touching externally

WebLet O be the centre of the circle and AB be the tangent segment drawn from an external point A touching the circle at B. The tangent at any point of a circle is perpendicular to the radius through the point of contact. ∴ ∠ABO = 90º In right ∆ABO, OA 2 = AB 2 + OB 2 ⇒ OB = OA 2-AB 2 ⇒ OB = 12. 5 2-12 2 ⇒ OB = 156. 25-144 ⇒ OB = 12 ...
