Given that KLNP is a rhombus, calculate
- ∠t
- ∠u
(a)
∠KRP = ∠LRS = 99° (Vertically opposite angles)
∠t
= 180° - 99° - 14°
= 67° (Angles sum of triangle)
(b)
∠PNL
= 180° - 14° - 14°
= 152° (Angles sum of triangle)
∠u
= 360° - 99° - 152° - 14°
= 95° (Sum of Angles in a quadrilateral)
Answer(s): (a) 67°; (b) 95°
