opposite angles of a parallelogram is equal
=>2x + 35 = 3x - 5
=> X = 40
angle D = 2×40 + 35 = 80+35 = 115°
angle B = 3 × 40 - 5 = 120-5 = 115°
=>2x + 35 = 3x - 5
=> X = 40
angle D = 2×40 + 35 = 80+35 = 115°
angle B = 3 × 40 - 5 = 120-5 = 115°

angle b = angle d (opposite angle of a parallelogram are equal)
3x-5=2x+35
3x-2x=35+5
x=40
angle b will be 3x-5 is 3*40-5
120-5
115°
angle d will be 2x+35
2*40+35
80+35
115°
3x-5=2x+35
3x-2x=35+5
x=40
angle b will be 3x-5 is 3*40-5
120-5
115°
angle d will be 2x+35
2*40+35
80+35
115°
