In the figure, YSUX and YSTW are parallelograms. Given that ∠USV = 11°, ∠YXW = 67° and YWX is an isosceles triangle where YW = YX. Find
- ∠SVU
- ∠YSV
(a)
∠SUX
= 180° - 67°
= 113° (Interior angles)
∠SVU
= 180° - 113° - 11°
= 56° (Angles sum of triangle)
(b)
∠YSV
= ∠SVU
= 56° (Alternate angles)
Answer(s): (a) 56°; (b) 56°
