I need help with these questions

The error is the number of sides, it should be 9 sides and not 25. Correct is 1 260 degrees

Step-by-step explanation:

The error is the number of sides, it should be 9 sides and not 25.

Polygon sum of interior angles formula: 180 x (n-2)

So here n = 9 (sides)

180 x (9-2)

180 x 7 = 1 260 degrees

sum of interior angles = 180 * n - 2

n = number of sides

in this case, the shape has 9 sides so n = 9

so the correct answer should be

= 180 * (9-2)

= 180 * 7

= 1260

answer: 43/157

this is the answer and if you try to prove me wrong your a meanie

easy math just plug in a and b
