In the ABSD parallelogram, angles A and B are referred to as 2 to 3. Find the standard measure of the angle C.

Let the value of the angle BAD = 2 * X0, then, by condition, the angle ABC = 3 * X0.

In a parallelogram, the sum of adjacent angles is 180, then 2 * X + 3 * X = 180.

5 * X = 180.

X = 180/5 = 36.

Angle BAD = 2 * 36 = 72.

In a parallelogram, opposite angles are equal, then the angle BСD = BAD = 72.

Answer: Angle C is 72.
