FGHJ is a parallelogram. FJK and GLK are straight lines. Find the values of
- ∠b
- ∠e
- ∠d
- ∠c
(a)
∠b
= 180° - 50° - 56°
= 74° (Interior angles)
(b)
∠LFG = ∠LGF = 50° (Isosceles triangle)
∠e
= 180° - 56° - 50° - 50°
= 24° (Interior angles)
(c)
∠d
= 180° - 50° - 50°
= 80° (Isosceles triangle)
(d)
∠c = 56° (Alternate angles)
Answer(s): (a) 74°; (b) 24°; (c) 80°; (d) 56°
