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 ∠s.
- Find ∠t.
(a)
∠ELN
= 90° - 78°
= 12°
∠s
= 90° - 12°
= 78°
(b)
∠EFJ = ∠FGH = 119° (Corresponding angles)
∠FJK
= 180° - 119°
=61° (Interior angles)
∠t
= 360° - 84° - 61°
= 215°
Answer(s): (a) 78°; (b) 215°
