11x + 100° =540 °
11x=440°
x= 40°
7x=7×40
=280°
280 is the biggest angle of the pentagon

In a Pentagon ,
Sum of angles = (2n-4)*90
here,n=5,
:. sum of angles = (2*5-4)*90
= 6*90
= 540°
Let the other three angles be x,3x,7x
BTQ,
40+60+x+7x+3x= 540°
11x= 540-100
x= 440/11
x= 40
The Angles are 40°,60°,40°,120°,280°
The biggest angle is 280 °
