PSLE In the figure, MNPQ is a rectangle. The points S, T, and U lie on the rectangle MNPQ. QRS and URT are straight lines.
- Find ∠STR.
- Find ∠RQU.
(a)
∠NTU = ∠QUT = 88° (Alternate angles)
∠STR
= 88° - 47°
= 41°
(b)
∠SRT
= 180° - 91° - 41°
= 48° (Angles sum of triangle)
∠QRU = 48° (Vertically opposite angles)
∠ RQU
= 180° - 88° - 48°
= 44° (Angles sum of triangle)
Answer(s): (a) 41°; (b) 44°
