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 = 88° (Alternate angles)
∠KLJ
= 88° - 49°
= 39°
(b)
∠KJL
= 180° - 90° - 39°
= 51° (Angles sum of triangle)
∠HJM = 51° (Vertically opposite angles)
∠ JHM
= 180° - 88° - 51°
= 41° (Angles sum of triangle)
Answer(s): (a) 39°; (b) 41°
