Referring to the attached pic:

A quadrilateral ACQR is inscribed in a circle. Diagonals are drawn to intersect at T such that angle $\displaystyle ATR = 76^o$

Both S, P and B are points outside the circle.

AC and RQ are extended to meet at P such that angle $\displaystyle APR = 30^o$

CQ and AR are extended to meet at B such that angle $\displaystyle ABC = 46^o$

QC is extended to S, forming triangle SAC where SC = AC

Find the angle ASC.
