An interior angle of a regular polygon measures 170 degrees. how many sides does it have?

How many sides does it have is 36 sides

The regular polygon of n sides is:

a=(n-2)×180/2

Solve for  n

160=(n-2)×180/n

Multiply both sides by n

170n=(n-2)×180

Simplify

170n=180n-360

Subtract  from both sides

0=10n-360

Divide both sides by 10

n=360/10

n=36

Inconclusion How many sides does it have is 36 sides.
