Given that RSTU is a rhombus, calculate
- ∠y
- ∠z
(a)
∠RVU = ∠SVX = 101° (Vertically opposite angles)
∠y
= 180° - 101° - 22°
= 57° (Angles sum of triangle)
(b)
∠UTS
= 180° - 22° - 22°
= 136° (Angles sum of triangle)
∠z
= 360° - 101° - 136° - 22°
= 101° (Sum of Angles in a quadrilateral)
Answer(s): (a) 57°; (b) 101°
