Given that HKLN is a rhombus, calculate
- ∠s
- ∠t
(a)
∠HPN = ∠KPR = 112° (Vertically opposite angles)
∠s
= 180° - 112° - 15°
= 53° (Angles sum of triangle)
(b)
∠NLK
= 180° - 15° - 15°
= 150° (Angles sum of triangle)
∠t
= 360° - 112° - 150° - 15°
= 83° (Sum of Angles in a quadrilateral)
Answer(s): (a) 53°; (b) 83°
