PSLEIn the figure, TUVW is a parallelogram. TRW and RVS are straight lines. ∠SVW = 153°, ∠TWV = 43° and ∠TVR = 17°.
- Find ∠UVS.
- Find ∠UTV.
(a)
∠UVW
= 180° - 43°
= 137° (Interior angles)
∠UVS
= 360° - 153° - 137°
= 70° (Angles at a point)
(b)
∠WVR
= 180° - 153°
= 27°(Angles on a straight line)
∠UTV
= ∠TVW
= 27° + 17°
= 44° (Alternate angles)
Answer(s): (a) 70°; (b) 44°
