#### Two chords AB, CD of a circle intersect externally at point P. If PB = 7 cm, AB = 9 cm and PD = 6 cm, find CD.

**Solution:**

#### In the figure given below, chord AB and diameter PQ of a circle with centre O meet at X. If BX = 5 cm, OX = 10 cm and.the radius of the circle is 6 cm, compute the length of AB. Also, find the length of tangent drawn from X to the circle.
