ѕum σf αll αnglєѕ = 360°

ѕσ,

70° + 95° + 80° + fσurth αnglє = 360°

fσurth αnglє = 360° - 245°

fσurth αnglє = 115°

Answer 2

sum of the angle of quadrilateral is 360°
as if there is a polygon of n sides (n>=3),then the sum of the interior angles are (n-2)180
=>4-2*180=2*180
let the 4th angle be x
70+95+80+x=360
245+x=360
360-245=115

The answer is 115
