Answer: the polygon has 20 sides.
Step-by-step explanation:
The formula for determining the sum of the measure of the interior angles in a regular polygon is expressed as (n - 2) × 180.
if the sum of the measures of the interior angles is 3960
degrees. This means that
(n - 2) × 180 = 3960
Expanding the brackets by applying the distributive property, it becomes
180n - 360 = 3960
180n = 3960 - 360
180n = 3600
Dividing both sides by 180, it becomes
n = 3600/180
n = 20
Answer:
Your answer is: k = 5+12/x
Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:
10
Step-by-step explanation:
F(0) = 3^2+1=9+1=10
That depends on if there is a 90-degree angle within the triangle or not.
Hello there!
On those type of angles, the angles that are facing each other is equal to another.
So you can set up the equation like this :
10x + 1 = 12x - 5
-2x = -6
x = 3
So the answer is x = 3.
In some problems, you have to find the angle.
Then you just simply substitute 3 into x.
10x + 1
10(3) + 1
30 + 1
31
12x - 5
12(3) - 5
36 - 5
31
The angles are 31° and 31°.
Hope this helped! :)
