Question

The angle of quadrilateral are 100 ,98,92 then find fourth angle

Answer 1

let the 1st angle = 100

           2nd angle = 98

            3rd angle=92

therefore, 4th angle = 100+98+92=360

                                 = 290 = 360

                                = 360-290 =70 answer

Answer 2

70° is the answer

100° + 98° + 92 + angle 4 = 340°

angel 4 = 360° - 280

angle 4 = 70°
