Detailed Solution

Given, a heptagon.
The number of sides in a pentagon is n=7.
We know that,
Exterior angle of a n-sided polygon

= 3600 n

, where, n is the number of sides of any given polygon.
Substituting

n = 7

in the formula,
Exterior angle of the pentagon

= 36007

Exterior angle of the heptagon

= 51.43 0

.
Hence, the exterior angle of the heptagon

51.43 0

.
Therefore, option 2 is correct.
