<span>So it's length would be half of the length of the base </span>\frac{14}{2} = 7 <span>=> </span>7^{2} + x^{2} = 14^{2} => 49 +  = 196 => x^2 = 147 => x = sqrt 147 = 7 * sqrt 3 . So the altitude is equal to 7 * sqrt 3. An approximate value to that would be 12.12

Hope this helps

How do i rewrite this in function form ?
Tema [17]
So now its-x + y = 6 &#10;
but you want it in y=mx+b so 

add x to both sides so that you have y on its own 
so now it's y = 6+x

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
