TUVW is a parallelogram. TWX and UYX are straight lines. Find the values of
- ∠r
- ∠v
- ∠t
- ∠s
(a)
∠r
= 180° - 51° - 56°
= 73° (Interior angles)
(b)
∠YTU = ∠YUT = 51° (Isosceles triangle)
∠v
= 180° - 56° - 51° - 51°
= 22° (Interior angles)
(c)
∠t
= 180° - 51° - 51°
= 78° (Isosceles triangle)
(d)
∠s = 56° (Alternate angles)
Answer(s): (a) 73°; (b) 22°; (c) 78°; (d) 56°
