Answer:

112

Explanation:

Sum of interior angles in quadrilaterial = 360

360 - 100 - 104 - 44 = 112

Explanation:

Let the 4th angle = x

Now,

x + 100 + 104 + 44 = 360° ( the sum of interior angle of quadrilateral is 360°)

x + 248 = 360°

x = 360° - 248

x = 112

Hence, the fourth angle is 112....
