In a triangle PQR, side QR is extended to S to form exterior angle PSQ = 125°, and side QP is extended to T to form exterior angle PRT = 110° (where T lies on line extend beyond R/P). If exterior angles at Q and R are 125° and 110° respectively, what is the value (in degrees) of angle SPR?

If B is the center of a circle and lines AD and CD are tangent segments drawn from an external point D, then which of the following classifications apply to quadrilateral ABCD? (a) Kite (b) Cyclic quadrilateral (c) Rhombus (d) Trapezium
