PSLE In the figure, GHJK is a rectangle. The points M, N, and P lie on the rectangle GHJK. KLM and PLN are straight lines.
- Find ∠MNL.
- Find ∠LKP.
(a)
∠HNP = ∠KPN = 82° (Alternate angles)
∠MNL
= 82° - 49°
= 33°
(b)
∠MLN
= 180° - 94° - 33°
= 53° (Angles sum of triangle)
∠KLP = 53° (Vertically opposite angles)
∠ LKP
= 180° - 82° - 53°
= 45° (Angles sum of triangle)
Answer(s): (a) 33°; (b) 45°
