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 ∠j.
- Find ∠k.
(a)
∠WCE
= 90° - 77°
= 13°
∠j
= 90° - 13°
= 77°
(b)
∠WXA = ∠XYZ = 120° (Corresponding angles)
∠XAB
= 180° - 120°
=60° (Interior angles)
∠k
= 360° - 89° - 60°
= 211°
Answer(s): (a) 77°; (b) 211°
