Two unequal angles of a parallelogram are in the ratio 2 : 3. Find all its angles in degrees.

Answer :

Let, A = 2x and B = 3x


Now,


AHB = 180o (Co. interior angles are supplementary)


2x + 3x = 180o


5x = 180o


x = 36o


A = 2x = 72o


B = 3x = 108o


Now,


A = C = 72o(Opposite sides angles of a parallelogram are equal)


B = D = 108o(Opposite sides angles of a parallelogram are equal)
