Given that KLNP is a rhombus, calculate
- ∠t
- ∠u
(a)
∠KRP = ∠LRS = 102° (Vertically opposite angles)
∠t
= 180° - 102° - 19°
= 59° (Angles sum of triangle)
(b)
∠PNL
= 180° - 19° - 19°
= 142° (Angles sum of triangle)
∠u
= 360° - 102° - 142° - 19°
= 97° (Sum of Angles in a quadrilateral)
Answer(s): (a) 59°; (b) 97°
