The regular polygon has 72 sides ⇒ A

Step-by-step explanation:

The rule of the measure of an interior angle of a regular polygon is:

The measure of each angle = , where n is the number of its sides

Let us use this rule to solve the question

∵ The polygon is regular

∴ All sides are equal in lengths

∴ All interior angles are equal in measures

∵ The measure of an interior angle of the regular polygon is 175°

→ Substitute it in the rule above to find n

∴ 175° =

→ Multiply both sides by n to cancel the denominator in the right side

∴ 175 n = (n - 2)180

→ Multiply the bracket by 180

∴ 175 n = n(180) - 2(180)

∴ 175 n = 180 n - 360

→ Subtract 180 n from both sides

∵ 175 n - 180 n = 180 n - 180 n - 360

∴ - 5 n = - 360

→ Divide both sides by -5

∵

∴ n = 72

∴ The regular polygon has 72 sides

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
