In the figure, QRST and RVWX are two rhombuses. If ∠VWX = 120° and ∠QTS = 96°, calculate
- ∠WVX
- ∠WSR
- ∠XYS
(a)
∠WVX
= (180° - 120°) ÷ 2
= 30° (Isosceles triangle)
(b)
∠WSR = ∠QTS = 96° (Corresponding angles)
(c)
∠XYS
= 96° - 30°
= 66° (Exterior angle of a triangle)
Answer(s): (a) 30°; (b) 96°; (c) 66°
