In the figure, not drawn to scale, two rectangles, DELM and KLNP overlap each other as shown. Given that DG // KJ and FJ // GH.
- Find ∠f.
- Find ∠g.
(a)
∠ELN
= 90° - 77°
= 13°
∠f
= 90° - 13°
= 77°
(b)
∠EFJ = ∠FGH = 120° (Corresponding angles)
∠FJK
= 180° - 120°
=60° (Interior angles)
∠g
= 360° - 84° - 60°
= 216°
Answer(s): (a) 77°; (b) 216°
