उत्तर
\[\text{ Two adjacent angles of a parallelogram add up to } 180° . \]
\[\text{ Let x be the angle } . \]
\[ \therefore x + \frac{2x}{3} = 180°\]
\[\frac{5x}{3} = = 180°\]
\[x = 72°\]
\[\frac{2x}{3} = \frac{2 \times 72°}{3} = 108°\]
\[\text{Thus, two of the angles in the parallelogram are 108° and the other two are }72° .\]
