In the given parallelogram, we can see that 9x° & 6x° are adjacent angles. 2 adjacent angles in a parallelogram sum up to 180°. So,
9x° + 6x° = 180°
15x° = 180°
x = 180/15
x = 12
Now,
6x° = 6 × 12 = 72°
9x° = 9 × 12 = 108°.
=》The value of 'x' is 12 & the measure of each labelled angle is 72° & 108°.
