UVWX is a rhombus, RSX and VSW are straight lines. If VS = SX, ∠SXW = 21° and ∠TVW = 27°, find
- ∠SWX
- ∠TRS
(a)
∠SWX
= 86° - 21°
= 65° (Exterior angle of a triangle)
(b)
∠VRS
= 86° - 27°
= 59° (Exterior angle of a triangle)
∠TRS
= 180° - 59°
= 121° (Angles on a straight line)
Answer(s): (a) 65°; (b) 121°
