Opposite angles of parallelogram are equal
So 63 - 3x = 4x - 7
=> 7x = 70
=> x = 10
4x-7= 40-7= 33
(180-33)= 147
So two angles are 33 degree each and other two angles are 147 degree each
So 63 - 3x = 4x - 7
=> 7x = 70
=> x = 10
4x-7= 40-7= 33
(180-33)= 147
So two angles are 33 degree each and other two angles are 147 degree each
