Given that LNPR is a rhombus, calculate
- ∠u
- ∠v
(a)
∠LSR = ∠NST = 106° (Vertically opposite angles)
∠u
= 180° - 106° - 21°
= 53° (Angles sum of triangle)
(b)
∠RPN
= 180° - 21° - 21°
= 138° (Angles sum of triangle)
∠v
= 360° - 106° - 138° - 21°
= 95° (Sum of Angles in a quadrilateral)
Answer(s): (a) 53°; (b) 95°
