Given that LNPR is a rhombus, calculate
- ∠u
- ∠v
(a)
∠LSR = ∠NST = 101° (Vertically opposite angles)
∠u
= 180° - 101° - 10°
= 69° (Angles sum of triangle)
(b)
∠RPN
= 180° - 10° - 10°
= 160° (Angles sum of triangle)
∠v
= 360° - 101° - 160° - 10°
= 89° (Sum of Angles in a quadrilateral)
Answer(s): (a) 69°; (b) 89°
