In the figure, SU is parallel to WV and SX is parallel to TY. SXW is a straight line, ∠SXY = 93°. ∠XST = 94° and the sum of ∠TUV and ∠VWX is 141°. Find
- ∠XYT
- ∠WVU
(a)
∠XYT
= 180° - 93°
= 87° (Interior angles)
(b)
∠WVU
= 360° - 141° - 94°
= 125° (Sum of angles in a quadrilateral)
Answer(s): (a) 87°; (b) 125°
