An octagon has seven sides which have a length of k feet. The eighth side has a length of 3.9 feet, as shown below. The perimeter of the octagon is 27.7 feet. What is the value of k?

K is 3.4 feet

Step-by-step explanation:

To find the perimeter of the octagon, we add up the lengths of all the sides

For this particular octagon;

7 * k + 3.9 = 27.7

7k + 3.9 = 27.7

7k = 27.7-3.9

7k = 23.8

k = 23.8/7

k = 3.4 feet

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
