Question

9. In a parallelogram, a pair of adjacent angles differs by 40°. Find all the angles of the parallelogram.
​

Answer 1

Answer:

70°, 110°, 70°, 110°

Step-by-step explanation:

x+×+40 = 180° (Co interior angles)

=> 2x = 140°

=>x = 70°

angles = x, x+40, (180-x), (180- (x+40))

Answer 2

.

Answer:

In a parallelogram any two adjacent angles add up to 180°(supplementary angles).So let one angle be x.Therefore the other angle will be(180-x).

In a parallelogram any two adjacent angles add up to 180°(supplementary angles).So let one angle be x.Therefore the other angle will be(180-x).therefore x=110° and 180°-x=180-110= 70
