\frac{4}{10} = \frac{2}{5}

First, I have to reduce 4/10 into 2/5 by dividing 4/10 by 2
10.4 = 10\frac{4}{10}

= 10\frac{2}{5}

So the answer is 10\frac{2}{5}

Given the regular octagon shown below, what is the measure of angle x?
vladimir1956 [14]

Answer:

x=45°

Step-by-step explanation:

The angle shown in the figure is known as an external angle.

Also, <u>in a regular polygon (like the regular octagon) the sum of all the exterior angles is the same regardless of the number of sides of the figure</u>:

360°

And to find the measure of a single external angle (such as the angle x shown in the figure) we must <u>divide 360 ° by the number of sides n:</u>

\frac{360}{n}

and for the regular octagon, since it has 8 sides:

n=8

so the value of x is:

x=\frac{360}{n}\\ \\x=\frac{360}{8}\\ \\x=45°

the measure of angle x is 45° which is the second option
