anushka9271: thanks

vimalkumar4702sh: daspragti, kindly change the RHS of your equation to 360°

daspragati: x + 2x + x+ 20 + 60 = 360 degree
solving this you'll x = 70 degree

Answer:

120°+y=180°(Linear pair)

y=180°-120°

y=60°

x+2x+x+20+y=360°(sum of angles of quadrilateral =360°)

4x+20°+60°=360°

4x+80°=360°

4x=360°-80°

4x=280°

x=280°/4

x=70°

therefore, x=70°

2x=2×70°=140°

x+20=70°+20°=90°

hope it helps you and don't forget to follow mè
