FGHJ is a parallelogram. FJK and GLK are straight lines. Find the values of
- ∠v
- ∠y
- ∠x
- ∠w
(a)
∠v
= 180° - 51° - 56°
= 73° (Interior angles)
(b)
∠LFG = ∠LGF = 51° (Isosceles triangle)
∠y
= 180° - 56° - 51° - 51°
= 22° (Interior angles)
(c)
∠x
= 180° - 51° - 51°
= 78° (Isosceles triangle)
(d)
∠w = 56° (Alternate angles)
Answer(s): (a) 73°; (b) 22°; (c) 78°; (d) 56°
