In the figure, QRST and RVWX are two rhombuses. If ∠VWX = 111° and ∠QTS = 97°, calculate
- ∠WVX
- ∠WSR
- ∠XYS
(a)
∠WVX
= (180° - 111°) ÷ 2
= 34.5° (Isosceles triangle)
(b)
∠WSR = ∠QTS = 97° (Corresponding angles)
(c)
∠XYS
= 97° - 34.5°
= 62.5° (Exterior angle of a triangle)
Answer(s): (a) 34.5°; (b) 97°; (c) 62.5°
