PSLE In the figure, RSTU is a rectangle. The points W, X, and Y lie on the rectangle RSTU. UVW and YVX are straight lines.
- Find ∠WXV.
- Find ∠VUY.
(a)
∠SXY = ∠UYX = 88° (Alternate angles)
∠WXV
= 88° - 57°
= 31°
(b)
∠WVX
= 180° - 92° - 31°
= 57° (Angles sum of triangle)
∠UVY = 57° (Vertically opposite angles)
∠ VUY
= 180° - 88° - 57°
= 35° (Angles sum of triangle)
Answer(s): (a) 31°; (b) 35°
