Answer:
[tex]245^\circ[/tex]
Step-by-step explanation:
Add two lines as shown in the attached image. Now the polygon is divided up into 3 triangles. The sum of angles of a triangle is 180 degrees.
The angle sum in all 3 triangles is 3 x 180 = 540 degrees.
The sum of the angles given in the figure is 295 degrees. Subtract this from the 540 degrees to get the "missing" angle, x.
x = 540 - 295 = 245 degrees.
