    (a) use angle in alternate segment (angle PQV = angle VTQ) (b) TVQ=90 (angle in semi-circle), as it said TWQ is a diameter then find angle SVQ then use angle in same segment to find y (angle QVS = angle QTS) (c) consider triangle TVS, find angle TSV first, then using the fact that quad TUVS is cyclic quad, angle VUT + angle TSV = 180 (opp angles, cyclic quad)
