Given that GHKL is a rhombus, calculate
- ∠r
- ∠s
(a)
∠GNL = ∠HNP = 109° (Vertically opposite angles)
∠r
= 180° - 109° - 25°
= 46° (Angles sum of triangle)
(b)
∠LKH
= 180° - 25° - 25°
= 130° (Angles sum of triangle)
∠s
= 360° - 109° - 130° - 25°
= 96° (Sum of Angles in a quadrilateral)
Answer(s): (a) 46°; (b) 96°
