Answer:
ABCD is a parallelogram
A=2x
B=3x
A and B are adjacent angles of a parallelogram
so , A+B=180(co interiorangles)
2x+3x=180
5x=180
x=180/5=36
so, B=3x=3×36=108

Answer:
let the angle of a and b be 2x and 3x respectively
2x + 3x = 180⁰ (sum of adjacent angles)
5x = 180⁰
x = 180/5
x = 36⁰
2x = 2 × 36 = 72⁰
3x = 3 × 36 = 108⁰
angle b = 108⁰
