An isosceles triangle containing two angles with equal measure is shown. The degree measure of eachtriangle's three interior angles and an extra angle is represented with variables. Find the measure of the three interior angles.

A triangle has angles labeled as follows: lower left, y degrees; top, x degrees; lower right, y degrees. A ray extends the left side of the triangle. Another ray extends the bottom side of the triangle and the angles labeled y degrees and (2 x minus 45) degrees are supplementary.
