Answer:

1260°

Step-by-step explanation:

Number of sides was given as 9, hence ( n= 9)

Sum of interior angle of a polygon can be determined using the expression below

[(2n-4)90°]

Substitute n=9

[((2×9) -4)) ×90]

= [(18-4)×90]

(14×90)=1260°

Hence, angle sum of polygon which had 9 sides​ is 1260°
