SOLUTION;
Let the adjacent angles of the ||gm be 2x & 1x
We know that the sum of adjacent angles of a ||gm = 180°
= 2x+1x=180°
= 3x=180°
=x=180/3
=x= 60°
Now, Adjacent angles are 2x= 2*60° =120°
&
1x= 1*60°= 60°
We know that the opposite angles of a parallelogram are equal.
So, The angles of a ||gm are 120°,60°,120°,60°
