Question

what is the answer for this question​

Answer 1

Step-by-step explanation:

9}a) let all three equal angles be x

we know that sum of all interior angles of a quadrilateral is 360.

so 111+x+x+x=360

111+3x=360

3x=360-111

3x=249

x=249/3

x=83

so al three equal angles are 83

hope it helped you,,if yes then mark like and brainliest.....

Answer 2

The interior angle sum of a quadrilateral is ( n - 2 ) 180 ((here n refers to number *))
111^. + 3x = 360^.
3x=360^. - 111^.
3x = 249
x = 249/3
x = 83
