In the figure, QRST and RVWX are two rhombuses. If ∠VWX = 110° and ∠QTS = 92°, calculate
- ∠WVX
- ∠WSR
- ∠XYS
(a)
∠WVX
= (180° - 110°) ÷ 2
= 35° (Isosceles triangle)
(b)
∠WSR = ∠QTS = 92° (Corresponding angles)
(c)
∠XYS
= 92° - 35°
= 57° (Exterior angle of a triangle)
Answer(s): (a) 35°; (b) 92°; (c) 57°
