In the figure, not drawn to scale, O is the centre of the semi circle and OKLM is a rhombus. ∠OMN = 29°. Find
- ∠t
- ∠v.
(a)
OM = ON = Radius
∠MON
= 180° - 29° - 29°
= 122° (Isosceles triangle)
∠t = ∠MON = 122° (Corresponding angles, KL//OM)
(b)
∠v
= 180° - 122°
= 58° (Interior angles, LM//KO)
Answer(s): (a) 122°; (b) 58°
