Question

Given the parallelogram ABCD state the measure angle B and angle C angle A 115 degree

Answer 1

angle A = C (opposite angles are equal)

115°= C

angle A + B = 180°(Linear pair)

115°+ B = 180°

B = 180°-115°

B = 65°

angle B = D ( opposite angles are equal)

65°= D

Thus, angle A = C = 115°

angle B = D = 65°

Answer 2

Answer: ∠a =115° then,

∠b = 180°-115° (being coordinate angles)

∠b = 65°

similarly,

∠c = ∠a (opposite angles of parallelogram)

therefore, ∠c = 115°//
