In the figure, not drawn to scale, O is the centre of the semi circle and OVWX is a rhombus. ∠OXY = 30°. Find
- ∠m
- ∠n.
(a)
OX = OY = Radius
∠XOY
= 180° - 30° - 30°
= 120° (Isosceles triangle)
∠m = ∠XOY = 120° (Corresponding angles, VW//OX)
(b)
∠n
= 180° - 120°
= 60° (Interior angles, WX//VO)
Answer(s): (a) 120°; (b) 60°
