In the figure, not drawn to scale, two rectangles, UVBC and ABDE overlap each other as shown. Given that UX // AZ and WZ // XY.
- Find ∠r.
- Find ∠s.
(a)
∠VBD
= 90° - 79°
= 11°
∠r
= 90° - 11°
= 79°
(b)
∠VWZ = ∠WXY = 121° (Corresponding angles)
∠WZA
= 180° - 121°
=59° (Interior angles)
∠s
= 360° - 83° - 59°
= 218°
Answer(s): (a) 79°; (b) 218°
