We know that.
A+B =180 (sum of adjacent angle of parallogram)
3x + 20 +2x - 30 =180
5x - 10 =180
x =190/5
x =38
Therefore A=134°
B = 46°
A+B =180 (sum of adjacent angle of parallogram)
3x + 20 +2x - 30 =180
5x - 10 =180
x =190/5
x =38
Therefore A=134°
B = 46°

hi friend ✋
in a parallelogram, adjacent angles (i.e <A and <B ) sum are 180°
then,
<A+<B=180°
then from the question
3x+20+2x-30=180°
5x-10=180°
5x=180+10
x=190/5
x=38
<A=3x+20=(3*38)+20=114+20=134°
<B=2x-30=(2*38)-30=76-30=46°
hope it helps
