Question

If the angle of an angle of a quadrilateral is 120 ° then the remaining angles will be treated

Answer 1

If the three of quadilareral are equal, consider each angle to be x

120°+x+x+x=360°
3x=360°-120°=240°
x=240°/3=80°
Remaining each angle will be 80°

Answer 2

hey '

plz mark as brain list

the sum of the angles of a quadrilateral is 360

so let the other 3 angles be x


x+x+x+120=360
3x+120=360
3x=360-120
3x=240
x=240/3
x=80

so the other angles r 80
