Question

ABCD is a parallelogram and angle A = 50 degrees then find angle B.
plzzz help me​

Answer 1

∠B = 130° if ABCD is a parallelogram and  ∠A = 50°

Step-by-step explanation:

ABCD is a parallelogram

in a parallelogram opposite angles are equal

=> ∠A = ∠C

& ∠B = ∠D

Sum of adjacent angles in parallelogram = 180°

=> ∠A + ∠B = 180°

=> 50° + ∠B = 180°

=> ∠B = 130°

Answer 2

Answer:

Step-by-step explanation:

ABCD is a parallelogram

∠A is adjacent ∠B

Hence, the sum of adjacent angles in quadrilateral is 180˚

=> ∠A + ∠B = 180˚

=> 50˚ + ∠B = 180˚

=> ∠B = 180˚ - 50˚

=> ∠B = 130˚

Therefore, ∠B = 130˚
