TUVW is a rhombus, QRW and URV are straight lines. If UR = RW, ∠RWV = 20° and ∠SUV = 34°, find
- ∠RVW
- ∠SQR
(a)
∠RVW
= 83° - 20°
= 63° (Exterior angle of a triangle)
(b)
∠UQR
= 83° - 34°
= 49° (Exterior angle of a triangle)
∠SQR
= 180° - 49°
= 131° (Angles on a straight line)
Answer(s): (a) 63°; (b) 131°
