Neco Model Questions Vol1 2018 Mathematics Question 49
Practice objective / multiple choice question 49 from the 2018 Neco Model Questions Vol1 Mathematics examination.
A circle has centre \(O\) and radius \(13\) cm. A chord \(AB\) is at a perpendicular distance of \(10\) cm from \(O\). The line through \(O\) perpendicular to \(AB\) meets the circle at points \(C\) and \(D\). A point \(P\) lies on the extension of \(OC\) beyond \(O\) such that \(OP = 20\) cm. (i) Find the length of the tangent from \(P\) to the circle (give your answer to two decimal places). (ii) Let \(Q\) be the intersection of line \(OP\) with chord \(AB\). Find the length \(PQ\) (in centimetres).
