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° - 52°
= 29°
(b)
∠MLN
= 180° - 91° - 29°
= 60° (Angles sum of triangle)
∠KLP = 60° (Vertically opposite angles)
∠ LKP
= 180° - 81° - 60°
= 39° (Angles sum of triangle)
Answer(s): (a) 29°; (b) 39°
