PSLE In the figure, FGHJ is a rectangle. The points L, M, and N lie on the rectangle FGHJ. JKL and NKM are straight lines.
- Find ∠LMK.
- Find ∠KJN.
(a)
∠GMN = ∠JNM = 88° (Alternate angles)
∠LMK
= 88° - 53°
= 35°
(b)
∠LKM
= 180° - 92° - 35°
= 53° (Angles sum of triangle)
∠JKN = 53° (Vertically opposite angles)
∠ KJN
= 180° - 88° - 53°
= 39° (Angles sum of triangle)
Answer(s): (a) 35°; (b) 39°
