Sum of adjacent angles =180
=> 4x-15+5x-3=180
=>9x-18=180
=>9x=198
=>x=22
opposite angles are equal
therefore angles are 73,107,73,107

We know that sum of adjacent angles in a parallelogram is 180 degrees.
4x-15+5x-3=180
9x-18=180
9x=198
x=22
therefore,angles in given parallelogram are
73,107,73,107[since,opp.angles in a parallelogram are equal]
