Step-by-step explanation:
In parallelogram the sum of adjacent Angles is 180° so
angle a + angle b= 180°
angle b + angle c=180°
=3x+15+2y+15=180°
=3x +2y+30=180
3x+2y=150........equation 1
=2x+35+2y+15=180°
2×+2y=180-50
2x+2y=130°.........equation 2
by solving equation 1 and 2
3x+2y=150
2x+2y=130
__________
x=20
by substituting x=20 in equation 2 we get
2(20)+2y=130
40+2y=130
2y=130-40
2y=90
y=90/2
y=45
Hence , x=20 y=45
