Answer:
Largest angle is 174 degree. x = 35.03 (if we multiply this by 5 = 175.15-1.08134979136 we get 174.068650209 angle (174 degree). This will be the largest angle as nothing over 175.15 works when we multiply 35.03 x 1.08134979136 and by 2 and by 3 and by 4 and add to 174.068650209. This equates to 540 degree which is what this sum was all about.
Therefore x = 35.03 $=1.08134979136 and largest angle possible is 174 degree (which is not the maximum angle in a pentagon but it is close to it considering we are multiplying by a same number each time and inkeeping with x x $ or x-$ or x+$= angle.
