PSLE In the figure, EFGH is a rectangle. The points K, L, and M lie on the rectangle EFGH. HJK and MJL are straight lines.
- Find ∠KLJ.
- Find ∠JHM.
(a)
∠FLM = ∠HML = 84° (Alternate angles)
∠KLJ
= 84° - 57°
= 27°
(b)
∠KJL
= 180° - 93° - 27°
= 60° (Angles sum of triangle)
∠HJM = 60° (Vertically opposite angles)
∠ JHM
= 180° - 84° - 60°
= 36° (Angles sum of triangle)
Answer(s): (a) 27°; (b) 36°
