PSLE In the figure, NPQR is a rectangle. The points T, U, and V lie on the rectangle NPQR. RST and VSU are straight lines.
- Find ∠TUS.
- Find ∠SRV.
(a)
∠PUV = ∠RVU = 84° (Alternate angles)
∠TUS
= 84° - 47°
= 37°
(b)
∠TSU
= 180° - 90° - 37°
= 53° (Angles sum of triangle)
∠RSV = 53° (Vertically opposite angles)
∠ SRV
= 180° - 84° - 53°
= 43° (Angles sum of triangle)
Answer(s): (a) 37°; (b) 43°
