a = 65° (Vertically opp. Angles)

b = 65° (Alternate angle to a)

c = 115° (Corresponding angle to the corresponding angle which is marked as 115°)

c + e = 180°

115° + e = 180°

e = 65°

d = 65° (Alternate angle to e)

∠F=180-115(straight angle)

=65

∠F=∠D=65°(opp angles of a parallelogram are equal)

∠F=∠E=65°(alternate angle of ║gm)

∠E=∠C=65°(alternate interior angle of ║gm)

∠F+∠G+∠A=180°(sum of interior angle of Δ)

∠G=180-(∠A+∠F)====>180-130=50°

∠G+∠B+∠E=180°(straight angle)

∠B=180-(∠G+∠E)

=180-115

=65°
