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 = 85° (Alternate angles)
∠WXV
= 85° - 48°
= 37°
(b)
∠WVX
= 180° - 91° - 37°
= 52° (Angles sum of triangle)
∠UVY = 52° (Vertically opposite angles)
∠ VUY
= 180° - 85° - 52°
= 43° (Angles sum of triangle)
Answer(s): (a) 37°; (b) 43°
