Given that LNPR is a rhombus, calculate
- ∠u
- ∠v
(a)
∠LSR = ∠NST = 112° (Vertically opposite angles)
∠u
= 180° - 112° - 25°
= 43° (Angles sum of triangle)
(b)
∠RPN
= 180° - 25° - 25°
= 130° (Angles sum of triangle)
∠v
= 360° - 112° - 130° - 25°
= 93° (Sum of Angles in a quadrilateral)
Answer(s): (a) 43°; (b) 93°
