Step-by-step explanation:
The sum of the measures of the interior angles of each convex n-sided polygon is always equal to
1. A pentagon is 5-sided polygon, then the sum of the measures of the interior angles of pentagon is
2. An octagon is 8-sided polygon, then the sum of the measures of the interior angles of octagon is
3. A dodecagon is 12-sided polygon, then the sum of the measures of the interior angles of dodecagon is
4. For 40-sided polygon the sum of the measures of the interior angles is

6. For 100-sided polygon the sum of the measures of the interior angles is
Answer:
Solution: ,
Step-by-step explanation:
<u>System of Equations</u>
Solve the system:
x + 4y = 14
3x - 2y = 7
using the elimintation method.
To use the elimination method, we must add or subtract both equations in such a way that one of the variables goes away, and only one remains.
It requires to multiply one of them by a specific factor to match the coefficients. For example, multiply the first equation by -3:
-3x - 12y = -42
And add it to the second:
3x - 2y = 7
To result:
-14y = -35
Divide by -14:
Simplifying:
Now calculate x:
Solution: ,
