C
Step-by-step explanation:
A pentagon has 5 sides. Given that it is a regular pentagon, these 5 sides are equal.
The perimeter is the total length of all the sides of the pentagon. Since these 5 sides are all equal, we can divide the perimeter by 5 to obtain the length of a side of the pentagon.
Perimeter= 10x +15
Length of each side
= (10x +15) ÷5
= 2x +3
Cos = adjacent / hypotenuse
cos 25° = 4 / AB
cos 25° • AB = 4 / AB • AB
AB cos 25° ÷ cos 25° = 4 ÷ cos 25°
AB = 4/cos 25°
AB = 4.41 (nearest hundredth)
