Question

if two angles of a quadrilateral are 80 degree and 110 degree, the sum of the remaining angles will be ______
​

Answer 1

Solution :

We know that , sum of all angles of quadrilateral is 360

Thus ,

80 + 110 + C + D = 360

C + D = 360 - 190

C + D = 170

f two angles of a quadrilateral are 80 degree and 110 degree, the sum of the remaining angles will be 170
