Answer 2

Answer:

Let the four angle of a quadrilateral be x

First angle of a quadrilateral is 80 degree

Second angle of a quadrilateral is 95 degree

Third angle of a quadrilateral is 112 degree

we know that sum of angles of a quadrilateral is 360 degree

80 degree + 95 degree + 112 degree + x = 360 degree

287 degree + x =360 degree

x = 360 degree - 287 degree

x= 73 degree Answer
