70° is the answer.
100°+98°+92+angle4=360°
angle 4 =360°-280
angle 4=70°
100°+98°+92+angle4=360°
angle 4 =360°-280
angle 4=70°

given angles :
1st = 100°
2nd = 98°
3rd = 92°
4th = ?
sum of all angles in a quadrilateral =360
∠1 +∠2 +∠3 + ∠4 = 360°
100°+98°+92°+∠4 = 360°
290° +∠4 = 360°
∠4 =360°-290°
∠4 = 70°
1st = 100°
2nd = 98°
3rd = 92°
4th = ?
sum of all angles in a quadrilateral =360
∠1 +∠2 +∠3 + ∠4 = 360°
100°+98°+92°+∠4 = 360°
290° +∠4 = 360°
∠4 =360°-290°
∠4 = 70°
