$$PQR$$ is an isosceles triangle where $$PQ = PR$$. $$X$$ is a point on the circumcircle of $$\triangle PQR$$, such that it being in the opposite region of $$P$$ with respect to $$QR$$. The normal drawn from the point $$P$$ on $$XR$$ intersects $$XR$$ at point $$Y$$. If $$XY = 10$$, then find the value of $$QX + RX$$.

its easy. extend XR to a point M such that RM=QX. Now try proving that Y is the mid point of XM.
