    The circle C has centre A(4,3) and passes through the point B(10, 5) .

    (a) Find an equation for C.

    The line L1 is the tangent to C at the point B.

    (b) Find an equation for L1

    The line L2 is parallel to L1 and passes through the mid-point of AB.

    Given that intersects C at the points P and Q,

    (c) Find the length of PQ, giving your answer in its simplest surd form.

    find the gradient AB
    the tangent at B will be perpendicular to AB (circle theorem)
