The sum of two op

Answer :

Let ABCD is a parallelogram.


B + D = 130°


B + B = 130° (Opposite angles of parallelogram are equal)


B = 65°


D = 65°


Now, B + C = 180° (sum of any two adjacent angles of a parallelogram is 180°)


C = 180° - B = 115°


Now, A = C = 115° (Opposite angles of parallelogram are equal)


Therefore, A = 115°, B = 65°, C = 115° and D = 65°.
