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 ∠m.
- Find ∠n.
(a)
∠XDF
= 90° - 78°
= 12°
∠m
= 90° - 12°
= 78°
(b)
∠XYB = ∠YZA = 125° (Corresponding angles)
∠YBC
= 180° - 125°
=55° (Interior angles)
∠n
= 360° - 84° - 55°
= 221°
Answer(s): (a) 78°; (b) 221°
