PSLEIn the figure, TUVW is a parallelogram. TRW and RVS are straight lines. ∠SVW = 151°, ∠TWV = 43° and ∠TVR = 22°.
- Find ∠UVS.
- Find ∠UTV.
(a)
∠UVW
= 180° - 43°
= 137° (Interior angles)
∠UVS
= 360° - 151° - 137°
= 72° (Angles at a point)
(b)
∠WVR
= 180° - 151°
= 29°(Angles on a straight line)
∠UTV
= ∠TVW
= 29° + 22°
= 51° (Alternate angles)
Answer(s): (a) 72°; (b) 51°
