[ Measuring the lengths of segments and the measures of angles. Adjacent angles.]

One of two adjacent angles is $30^{\circ}$ greater than the other. Find these angles.

#
The doubled smaller angle is equal to $180^{\circ}-30^{\circ}=150^{\circ}$. Therefore, the smaller angle is $75^{\circ}$.

## Answer

$105^{\circ}, 75^{\circ}$.
