    Two circles C1 and C2 meet at the points A and B. P is a point on the circumference of C1 such that PA is tangent to C2 at A. Q is a point on the circumference of C2 outside C1. QA is produced to meet C1 again at T so that anglePBT = 75 degrees. Find the size of angleABQ.

    Having just drawn it out a few times, no math, I get the sneaky
    feeling its the same triangle rotated on point B , so ABQ=75degrees.
