Given that KLNP is a rhombus, calculate
- ∠t
- ∠u
(a)
∠KRP = ∠LRS = 105° (Vertically opposite angles)
∠t
= 180° - 105° - 25°
= 50° (Angles sum of triangle)
(b)
∠PNL
= 180° - 25° - 25°
= 130° (Angles sum of triangle)
∠u
= 360° - 105° - 130° - 25°
= 100° (Sum of Angles in a quadrilateral)
Answer(s): (a) 50°; (b) 100°
