Sergio [31]

For a regular polygon with n sides, interior angle

= [(n-2) × 180°]/n

So, interior angle of this regular heptagon shape

= [(7 - 2) × 180°]/7

= (5 × 180°)/7

= 900°/7

= (900/7)°

A square patio has a perimeter of (8x + 48) feet. What is the length of the patio?
4vir4ik [10]

Answer:

2x+12

What is the range of the data below <br> A.2 <br> B.5<br> C.12<br> D.13
Degger [83]

Range of the data = 13

Solution:

To find the range of the given data:

Let us first define what is range.

Range:

The range of the data set is the difference between the highest value and lowest value of the data set.

i. e. Range = Highest value – Lowest value

In the given number line,

Highest value indicated = 115

Lowest value indicated = 102

Range of the data = 115 – 102

                              = 13

Range of the data = 13

Hence the range of the given data is 13.

Hope this helps :)
