Answer 2

Answer:

10 sides

Step-by-step explanation:

Solution :-

Given that,

Two angles of a polygon are right angle and the remaining are 160 degree each.

Let us consider 'n' to be the number of sides.

Sum of angles = 2 90°+(n−2)×160°

Sum = 180° + 160n - 340

As we know,

Sum of all angles of a polygon = 180°(n−2)

According to the question,

180n - 360° = 180° + 160n-340

180n−160n=180-340+360

20n=-160+360

20n=200

n=200/20

n=10

Therefore, the polygon has 10 sides.
