Solution:-
We will use the formula ,that is,=> 180(n-2)
Where n is equal to sides given.
1)5 \: sides \\  =  > 180(5 - 2) \\ =  >  180 \times 3 \\  =  > 540
Hence,
Interior angle is equal to 540°

2)9 \: sides \\  =  > 180(9 - 2) \\  =  > 180 \times 7 \\  =  > 1260
Hence,
Interior angle is 1260°

3)12 \: sides \\  =  > 180(12 - 2) \\  =  > 180 \times 10 \\  =  > 1800
Hence,
Interior angle is 1800°

We can also find out the interior angle of polygon by using formula:-
=>(2n-4) ×90°
