In the figure, YSUX and YSTW are parallelograms. Given that ∠USV = 11°, ∠YXW = 60° and YWX is an isosceles triangle where YW = YX. Find
- ∠SVU
- ∠YSV
(a)
∠SUX
= 180° - 60°
= 120° (Interior angles)
∠SVU
= 180° - 120° - 11°
= 49° (Angles sum of triangle)
(b)
∠YSV
= ∠SVU
= 49° (Alternate angles)
Answer(s): (a) 49°; (b) 49°
