Question

one side of a parallelogram is 100 degree find the measure of remaining three angles​

Answer 1

Answer:

80

Step-by-step explanation:

If we have a parallelogram with one side as 100° so we know that opposite angles in a parallelogram are equal so,angle A== angle C ==100°Let angle B=angle D=xAngle a + angleB+angle C+angle D=360°(A.S.P)100+x+100+x=360200+2x=3602x=360-2002x=160x=80angle B=angle D=80
