Given 2 adjacent angles of a parallelogram are (2y+10')and (3y-40'),
As we know,
opposite sides of a parallelogram are equal and parallel.
so the sum of the angles = 180°
as they lie at the same side of transversal
hence the equation is A/q :-
2y+10+3y-40=180
=>5y-30=180
=>5y=210
Y= 210/5
=42
Hence,
angles of the parallelogram are 94,86,94,86.
