1. Answer:

   144°

   Step-by-step explanation:

   Sum of angles of a quadrilateral =360°

   Let the required angle be x

   Therefore,

   36°+72°+108°+x=360°

   216°+x=360°

   x=144°

   Therefore the fourth angle is 144°

2. Answer:

   the sum of all four angle of a quadrilateral is 360 degree.

   36+72+108+x = 360.

   216 + X =360.

   X = 360 -216=144.

   hence the fourth angle is 144 degree.
