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 = 81° (Alternate angles)
∠MNL
= 81° - 56°
= 25°
(b)
∠MLN
= 180° - 90° - 25°
= 65° (Angles sum of triangle)
∠KLP = 65° (Vertically opposite angles)
∠ LKP
= 180° - 81° - 65°
= 34° (Angles sum of triangle)
Answer(s): (a) 25°; (b) 34°
