A rectangular pizza has a width of 5 in. and a length of 10 in. The pizza is cut into 8 congruent triangular slices. What is the perimeter of one slice of pizza to the nearest inch?

First I will cut this into 4 rectangles,2.5 by 5 each.

Now cut each rectangle into two triangles
base = 5
leg = 2.5
hypotenuse = sqrt(25+6.25)
add those up

. If the pizza is cut into 12 congruent pieces, how many degrees are in each central angle?

To find the perimeter of one slice of pizza, we need to determine the length of each side of the triangular slice.

First, we know that the width of the rectangular pizza is 5 inches and the length is 10 inches. We can use these measurements to find the dimensions of each triangular slice.

Since the pizza is cut into 8 congruent triangular slices, we can divide the width and length of the pizza by 2 to get the dimensions of each slice.

For the width of each triangular slice, we have: 5 inches / 2 = 2.5 inches.
For the length of each triangular slice, we have: 10 inches / 2 = 5 inches.

Now, we can use the dimensions of the triangular slice to find the perimeter.

The triangular slice has three sides. To find the perimeter, we add the lengths of the three sides.

The first side is the base of the triangle, which has a length of 2.5 inches.
The second side is one of the two equal legs of the triangle, which also has a length of 2.5 inches.
The third side is the other leg of the triangle, which has a length of 5 inches.

To find the perimeter: 2.5 inches + 2.5 inches + 5 inches = 10 inches.

Therefore, the perimeter of one slice of pizza is 10 inches.
