A regular octagon means that each of the 8 sides are equal. So, each side is 20 inches. To find the total amount of wire, you just find the perimeter:

8 * 20 = 160 inches of wire

It is important to note that since this is a regular shape, all sides are equal, which means that the perimeter is proportional to the side lengths.

inna [77]

Answer:

The constant of proportionality is 12.

Step-by-step explanation:

Let's take a look at the formula give to us:

48=4k

First, we have to isolate the variable, K, by dividing 4 on both sides.

48/4=4/4 k

48/4=12

12=k

We can check the answer by plugging it back into the equation:

12*4=48

48=48

Hence, the variable k equals 12.

What is the angles mSRW?
Scilla [17]

Answer:

126°

Step-by-step explanation:

(2x +18)° = (3x)°

2x + 18 = 3x

18 = 3x - 2x

18 = x

therefore, (3x)° = (3*18)°= (54)°

m\angle SRW + (3x)\degree = 180\degree \\m\angle SRW + 54\degree  = 180\degree \\m\angle SRW = 180\degree  - 54\degree  \\\huge\red{\boxed{m\angle SRW = 126\degree}}
