In the figure, not drawn to scale, two rectangles, WXDE and CDFG overlap each other as shown. Given that WZ // CB and YB // ZA.
- Find ∠e.
- Find ∠f.
(a)
∠XDF
= 90° - 79°
= 11°
∠e
= 90° - 11°
= 79°
(b)
∠XYB = ∠YZA = 124° (Corresponding angles)
∠YBC
= 180° - 124°
=56° (Interior angles)
∠f
= 360° - 86° - 56°
= 218°
Answer(s): (a) 79°; (b) 218°
