in a parrallogram
<B=<D <C =<A (opposite angles)
B= D so <B=115°
<B+<A=180°(angle at same side)
115+A=180
<A=180-115=65
<B=<D <C =<A (opposite angles)
B= D so <B=115°
<B+<A=180°(angle at same side)
115+A=180
<A=180-115=65

angle D = angle B .....vertically opposite angles
angle B = 115°.
angle D + angle C =180° ...angles in linear pair.
115°+angle C = 180°
angle C = 180 - 115°
angle C = 65°
angle C = angle A .....vertically opposite angles
angle A = 65°
angle B = 115°.
angle D + angle C =180° ...angles in linear pair.
115°+angle C = 180°
angle C = 180 - 115°
angle C = 65°
angle C = angle A .....vertically opposite angles
angle A = 65°
very nice answer... thank you so much
