The perimeter of a church window is 60 inches. if the window is in the shape of a regular pentagon, what is the length of each side of the window? a. 8 inches b. 10 inches c. 12 inches d. 6 inches

c. 12 inches

Step-by-step explanation:

Let's remember that a regular pentagon is a polygon with 5 equal sides.

We calculate the perimeter of a polygon by adding the length of the sides. In the case of a regular polygon, we just take the length of one side and multiply it by the amount of sides of the polygon.

As we have a regular pentagon, if we called S to the length of the sides, Perimeter = 5*S.

We know that the perimeter is 60 inches, so 5*S = 60.

We just need to find out the S by dividing by 5 on both sides of the equation:

5*S/5 = 60/5

S = 12

step-by-step explanation:

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
