Question

the measure of two angles of a quadrilateral are 80 degree and 120 degree find the measure of each of other remaining angles if the measure of those are seen​

Answer 1

Answer:

given measures of angles of quadrilateral are 80 and 120

To find : the remaining two angles

Formula : sum of all angles of quadrilateral = 360

80+120+x+x = 360

200+ 2x = 360

2x= 360-200

2x = 160

x= 160 / 2

x= 80

hence the remaining angles are 80 ,80
