In the figure, not drawn to scale, O is the centre of the semi circle and OWXY is a rhombus. ∠OYZ = 35°. Find
- ∠n
- ∠p.
(a)
OY = OZ = Radius
∠YOZ
= 180° - 35° - 35°
= 110° (Isosceles triangle)
∠n = ∠YOZ = 110° (Corresponding angles, WX//OY)
(b)
∠p
= 180° - 110°
= 70° (Interior angles, XY//WO)
Answer(s): (a) 110°; (b) 70°
