Answer 1

Answer:

Let two adjacent angles A and B of ∥gm ABCD be 3x and 2x respectively.

Since the adjacent angles of a parallelogram are supplementary.

∠A+∠B=180 o

⇒3x+2x=180 o

⇒5x=180 o

⇒x= 5/180 o

=36 o

∴∠3×36 o

=108 o

and, ∠B=2×36 o

=72 o

Since the opposite angles are equal in a parallelgram, therefore, ∠C=∠A=108 o

and ∠D=∠B=72 o

Hence, ∠A=108 o

,∠B=72 o

,∠C=108 o

and ∠D=72

Answer 2

Answer:

the some of two adjacent angles are 180°

so, 3x+2x=180°

5x=180°

x=36°

1st angle=2x=2×36=72°

2nd angle=3x=3×36=108°
