Given that HKLN is a rhombus, calculate
- ∠s
- ∠t
(a)
∠HPN = ∠KPR = 105° (Vertically opposite angles)
∠s
= 180° - 105° - 19°
= 56° (Angles sum of triangle)
(b)
∠NLK
= 180° - 19° - 19°
= 142° (Angles sum of triangle)
∠t
= 360° - 105° - 142° - 19°
= 94° (Sum of Angles in a quadrilateral)
Answer(s): (a) 56°; (b) 94°
