In the figure, not drawn to scale, two rectangles, YZFG and EFHJ overlap each other as shown. Given that YB // ED and AD // BC.
- Find ∠d.
- Find ∠e.
(a)
∠ZFH
= 90° - 79°
= 11°
∠d
= 90° - 11°
= 79°
(b)
∠ZAD = ∠ABC = 126° (Corresponding angles)
∠ADE
= 180° - 126°
=54° (Interior angles)
∠e
= 360° - 89° - 54°
= 217°
Answer(s): (a) 79°; (b) 217°
