Question

The adjacent angles of a parallelogram are in the ratio 3:6. Find the angles.

Answer 1

Answer:

We know that the sum of adjacent angles of a parallelogram is 180°

Let the adjacent angles be 3x & 6x

According to question,

3x+6x=180

9x=180

X=20°

Thus,

adjacent angles are 60 & 120 respectively.

Hope it helps you..

Answer 2

Answer:

Opposite angles of a parallelogram will be equal, so take 3x and 6x . So the oppsite sides of these will be equal. 3x+6x+3x+6x=2(3x+6x)=360 degrees

equate and find

2(9x)=360

9x=360/2=180

x=180/9

=20

3x=20*3=60

6x=20*6=120
