Answer 2

Answer:

BC= 5cm.

CD = 8 cm.

angle B = 130 degree.

Step-by-step explanation:

Given = ABCD is a parellelogram.

AD = 5cm.

AB = 8cm.

angle A = 50 degree.

To find : length of BC and C D.

measure of angle ABC.

Solu : In parellelogram ABCD,

AD = 5cm.

so, BC= 5 cm. and

AB = 8 cm. so, DC = 8cm.

( opposite sides are parellel and equal to each other.)

angle A + angle B = 180 degree. ( sum of the consecutive interior angles on the same side of a transversal )

50 degree + angle B = 180 degree.

angle B = 180 - 50.

angle B = 130 degree.

Angle A = 50 degree so, Angle C = 50 degree.

and Angle B = 130 degree, so, Angle D = 130 degree. ( opposite angles are equal. )
