In the figure, not drawn to scale, O is the centre of the semi circle and OVWX is a rhombus. ∠OXY = 29°. Find
- ∠r
- ∠s.
(a)
OX = OY = Radius
∠XOY
= 180° - 29° - 29°
= 122° (Isosceles triangle)
∠r = ∠XOY = 122° (Corresponding angles, VW//OX)
(b)
∠s
= 180° - 122°
= 58° (Interior angles, WX//VO)
Answer(s): (a) 122°; (b) 58°
