In the figure, not drawn to scale, O is the centre of the semi circle and OJKL is a rhombus. ∠OLM = 29°. Find
- ∠h
- ∠i.
(a)
OL = OM = Radius
∠LOM
= 180° - 29° - 29°
= 122° (Isosceles triangle)
∠h = ∠LOM = 122° (Corresponding angles, JK//OL)
(b)
∠i
= 180° - 122°
= 58° (Interior angles, KL//JO)
Answer(s): (a) 122°; (b) 58°
