PSLE In the figure, DEFG is a rectangle. The points J, K, and L lie on the rectangle DEFG. GHJ and LHK are straight lines.
- Find ∠JKH.
- Find ∠HGL.
(a)
∠EKL = ∠GLK = 82° (Alternate angles)
∠JKH
= 82° - 47°
= 35°
(b)
∠JHK
= 180° - 90° - 35°
= 55° (Angles sum of triangle)
∠GHL = 55° (Vertically opposite angles)
∠ HGL
= 180° - 82° - 55°
= 43° (Angles sum of triangle)
Answer(s): (a) 35°; (b) 43°
