Given that GHKL is a rhombus, calculate
- ∠r
- ∠s
(a)
∠GNL = ∠HNP = 104° (Vertically opposite angles)
∠r
= 180° - 104° - 17°
= 59° (Angles sum of triangle)
(b)
∠LKH
= 180° - 17° - 17°
= 146° (Angles sum of triangle)
∠s
= 360° - 104° - 146° - 17°
= 93° (Sum of Angles in a quadrilateral)
Answer(s): (a) 59°; (b) 93°
