Answer:

Step-by-step explanation:

Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as

1070=180(n-2) where n is the number of sides required here.

Making n the subject of the formula then following step by step

$n-2=\frac {1070}{180}$

$n=\frac {1070}{180}+2\\n=7.9444444444444\approx 8$

Therefore, the shape is octagon and it has 8 sides.
