In the figure, not drawn to scale, two rectangles, VWCD and BCEF overlap each other as shown. Given that VY // BA and XA // YZ.
- Find ∠r.
- Find ∠s.
(a)
∠WCE
= 90° - 74°
= 16°
∠r
= 90° - 16°
= 74°
(b)
∠WXA = ∠XYZ = 123° (Corresponding angles)
∠XAB
= 180° - 123°
=57° (Interior angles)
∠s
= 360° - 89° - 57°
= 214°
Answer(s): (a) 74°; (b) 214°
