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°

Hope my answer helps you if yes then pls mark my answer as brainliest

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.
