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 = 83° (Alternate angles)
∠MNL
= 83° - 50°
= 33°
(b)
∠MLN
= 180° - 91° - 33°
= 56° (Angles sum of triangle)
∠KLP = 56° (Vertically opposite angles)
∠ LKP
= 180° - 83° - 56°
= 41° (Angles sum of triangle)
Answer(s): (a) 33°; (b) 41°
