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 = 81° (Alternate angles)
∠TUS
= 81° - 56°
= 25°
(b)
∠TSU
= 180° - 93° - 25°
= 62° (Angles sum of triangle)
∠RSV = 62° (Vertically opposite angles)
∠ SRV
= 180° - 81° - 62°
= 37° (Angles sum of triangle)
Answer(s): (a) 25°; (b) 37°
