To construct a regular octagon, what measure would be necessary for each interior angle? Construct an angle of that measure.

svp [43]

Answer:

$135^\circ$

Step-by-step explanation:

Given that, a <em>regular octagon </em>is to be constructed.

To find:

Each angle in the octagon = ?

Solution:

We know that a regular triangle (polygon with 3 sides) has an interior angle of $60^\circ$ .

And a regular quadrilateral (square) has an interior angle of $90^\circ$ .

Therefore, formula for interior angle of a regular polygon with $n$ number of sides can be given as:

$\dfrac{n-2}{n}\times 180^\circ$

For an octagon, we have $n=8$ .

Value of Interior angle in a regular octagon:

$\dfrac{8-2}{8}\times 180^\circ=\dfrac{6}{8}\times 180^\circ=\bold{135^\circ}$

Kindly refer to the attached image for the angle of $135^\circ$

Rewrite the fraction as a decimal. <br> {57}{5}= 5 57

Inessa [10]

Answer: 11.4

Step-by-step explanation: In the fraction 57/5, 57 is the numerator and 5 is the denominator, the fraction bar means "divided by". Therefore, the fraction 57/5 is same as "57 divided by 5" or "57 ÷ 5".

When we calculated 57 divided by 5, we found that 57/5 in decimal form is:57 ÷ 5 = 11.4 Therefore, the decimal form of 57/5 is 11.4

VARVARA [1.3K]

Answer:

Emma should get $14.60, while Jessica should get $23.20 dollars

Step-by-step explanation:

Step 1:

Start with Emma. Emma has two vowels "E' and "A", so 6x2= 12.

Next, for the consonants, the name Emma has two "M"s, so 1.3x2=2.6. Then add 12 and 2.6 for $14.6, or $14.60.

Step 2:

Use Jessica

The name Jessica has 4 consonants, 2 being "S", one being "J", and one being "C", so 1.3x4=5.2. Next, the name Jessica has 3 vowels, so 6x3=18, then add 5.2 to 18 to get 23.2, or $23.20.

Thus, Emma should get $14.60 dollars, and Jessica should get $23.20 dollars
