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 = 87° (Alternate angles)
∠JKH
= 87° - 53°
= 34°
(b)
∠JHK
= 180° - 92° - 34°
= 54° (Angles sum of triangle)
∠GHL = 54° (Vertically opposite angles)
∠ HGL
= 180° - 87° - 54°
= 39° (Angles sum of triangle)
Answer(s): (a) 34°; (b) 39°
