Answer:
Sum of the interior angles = (n-2) x 180°
where 
n is the number of sides of the polygon 
Step-by-step explanation:
The formula for the sum of the interior angles of a polygon is:

where 
 is the sum of the interior angle of the polygon
 is the sum of the interior angle of the polygon 
 is the number of polygons
 is the number of polygons 
Let's check the formula using an example:
We want to find the sum of the interior angles of a square, we know that a square has 4 sides, so  .
.
Replacing values 



We can apply the same procedure to any convex polygon with n sides.
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Split the area into two sections by extending 6 in segment.
We get a rectangle of 5 in x 10 in and a trapezoid.
<u>Rectangle:</u>
<u>Trapezoid:</u>
- A = 1/2(b₁ + b₂)h
- A = 1/2((15 - 5) + 7)*(10 - 6) = 1/2*17*4 = 34 in²
<u>Total area:</u>

Answer:
355.94 cm²
Step-by-step explanation:
A = circle - rectangle
A = 11² * π - 4 * 6 = 121 * 3.14 - 24 = 355.94
 
        
             
        
        
        
Answer:

Step-by-step explanation:
<u>Linear Modeling</u>
It consist is setting up a linear relationship between two variables, given some experimental data. Only 2 points are needed to set up the equation of a line, but if more than 2 points are used, then the result should use statistical approaches like linear regression to find the best-fit line.
For the question at hand, Marty practices his piano lessons 11 minutes the week #1. It provides the first point (1,11). He practices 25 minutes per day on the third week. It gives us another point (3,25). This is enough to find the equation of a line. The general formula for a line, having two points (m1,w1) (m2,w2) is

Let's plug in our values

Simplifying:
