Given that RSTU is a rhombus, calculate
- ∠y
- ∠z
(a)
∠RVU = ∠SVX = 104° (Vertically opposite angles)
∠y
= 180° - 104° - 19°
= 57° (Angles sum of triangle)
(b)
∠UTS
= 180° - 19° - 19°
= 142° (Angles sum of triangle)
∠z
= 360° - 104° - 142° - 19°
= 95° (Sum of Angles in a quadrilateral)
Answer(s): (a) 57°; (b) 95°
