- A circle with centre \(A ( 3 , - 1 )\) passes through the point \(P ( - 9,8 )\) and the point \(Q ( 15 , - 10 )\)
- Show that \(P Q\) is a diameter of the circle.
- Find an equation for the circle.
A point \(R\) also lies on the circle. Given that the length of the chord \(P R\) is 20 units, - find the length of the shortest distance from \(A\) to the chord \(P R\).
Give your answer as a surd in its simplest form.
- Find the size of angle \(A R Q\), giving your answer to the nearest 0.1 of a degree.
