Three if the angles of a quadrilateral are 148, 104 and 36 whats the size of the 4th angle

The size of the 4th angle is 72.

Given:
1st angle = 148
2nd angle = 104
3rd angle = 36
shape = quadrilateral.

A quadrilateral is a shape that has 4 sides or edges, 4 corners or vertices.
It goes to show that it must also have 4 angles. These four angles must give the sum of 360°.

Since the first three angles are given, we can get the fourth angle by deducting the sum of the three angles from 360°

4th angle = 360° - 148° - 104° - 36°
                = 360° - 288°
4th angle = 72°

45 this is because of the agarose
