Given that FGHK is a rhombus, calculate
- ∠p
- ∠r
(a)
∠FLK = ∠GLN = 105° (Vertically opposite angles)
∠p
= 180° - 105° - 10°
= 65° (Angles sum of triangle)
(b)
∠KHG
= 180° - 10° - 10°
= 160° (Angles sum of triangle)
∠r
= 360° - 105° - 160° - 10°
= 85° (Sum of Angles in a quadrilateral)
Answer(s): (a) 65°; (b) 85°
