UVWX is a rhombus, RSX and VSW are straight lines. If VS = SX, ∠SXW = 20° and ∠TVW = 34°, find
- ∠SWX
- ∠TRS
(a)
∠SWX
= 88° - 20°
= 68° (Exterior angle of a triangle)
(b)
∠VRS
= 88° - 34°
= 54° (Exterior angle of a triangle)
∠TRS
= 180° - 54°
= 126° (Angles on a straight line)
Answer(s): (a) 68°; (b) 126°
