Given that GHKL is a rhombus, calculate
- ∠r
- ∠s
(a)
∠GNL = ∠HNP = 109° (Vertically opposite angles)
∠r
= 180° - 109° - 23°
= 48° (Angles sum of triangle)
(b)
∠LKH
= 180° - 23° - 23°
= 134° (Angles sum of triangle)
∠s
= 360° - 109° - 134° - 23°
= 94° (Sum of Angles in a quadrilateral)
Answer(s): (a) 48°; (b) 94°
