Question 3181
a pentagon is 5-sided. A 5-sided figure can be divided into 3 triangles, so total interior angles of a pentagon = 3*180 = 540.


Let smallest angle be x. Next will then be x+1, then x+2 etc.


so we get: x + x+1 + x+2 + x+3 + x+4 = 540
5x + 10 = 540
5x = 530
x = 106


so largest angle is 106+4 = 110
