9x -6 + 110 + 80 + 56 = 360
9x = 120
x = 13.333
helpme94:
it is supposed to be a direct answer. i am sorry but you may be wrong!
i use the sum of quadrilateral = 360
But the 70 is exterior
then its int. = 110
ok
usinf linear pair
ok

hey friend
here is your answer
we know that sum of linear angles is 180
so70+y=180. (suppose angle within 70°is y)
y=110°
now
we know that sum of all angles of a quadrilateral is 360°
so
80°+ 110° +56°+3x-6 =360°
(3x-6) +246° =360°
3x-6 =360°-246°
3x-6 =114°
3x=114+6
3x =120
x=120/3
x=40°
so the required angle is (3×40)-6
120-6 =114°
I hope you understand and it is helpful for you
