In the figure, QRS is parallel to VWX and the line VS cuts ∠RVX into half. Given that SV and RW are straight lines, ∠QRV = 48°, ∠VWU = 39° and ∠RUS = 110°, find
- ∠f
- ∠h
- ∠g
(a)
∠VUW = ∠RUS = 110° (Vertically opposite angles)
∠f
= 180° - 110° - 39°
= 31° (Angles sum of triangle)
(b)
∠h
= 180° - 31°
= 149° (Interior angles)
(c)
∠g
= 180° - 31° - 31° - 39°
= 93° (Angles sum of triangle)
Answer(s): (a) 31°; (b) 149°; (c) 93°
