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 = 87° (Alternate angles)
∠WXV
= 87° - 50°
= 37°
(b)
∠WVX
= 180° - 94° - 37°
= 49° (Angles sum of triangle)
∠UVY = 49° (Vertically opposite angles)
∠ VUY
= 180° - 87° - 49°
= 44° (Angles sum of triangle)
Answer(s): (a) 37°; (b) 44°
