In the figure, not drawn to scale, O is the centre of the semi circle and OWXY is a rhombus. ∠OYZ = 34°. Find
- ∠g
- ∠h.
(a)
OY = OZ = Radius
∠YOZ
= 180° - 34° - 34°
= 112° (Isosceles triangle)
∠g = ∠YOZ = 112° (Corresponding angles, WX//OY)
(b)
∠h
= 180° - 112°
= 68° (Interior angles, XY//WO)
Answer(s): (a) 112°; (b) 68°
