Final answer:
In a parallelogram, opposite angles are equal and adjacent angles are supplementary. So if angle A is 'x', then angles B and D are '180-x', and angle C is 'x'. Without further information, we can't provide numerical measures for angles B, C and D.
Step-by-step explanation:
In a parallelogram, opposite angles are equal and adjacent angles are supplementary. Let's designate the measure of angle A as 'x'.
Since angles A and B are supplementary, the measure of angle B is 180 - x. This makes sense since the sum of measures of angles forming a straight line is 180 degrees.
As C is opposite to A in the parallelogram, the measure of angle C is equal to that of angle A, which is 'x'. As per the properties of parallelogram, opposite angles are equal.
Similarly, the measure of angle D is equal to the measure of angle B because they are opposite angles, so it's 180 - x.
Without further information, such as the measure of angle A or some other details about the parallelogram, we can't provide numerical values for x, hence the measures of angles B, C and D.
