Answer:
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
5. For 52-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:
x = -2
Step-by-step explanation:
hello :
the system is : 3x-5y=10 ...(*)
-x+3y=-6...(**)
multiply (**) by : 3 you have : -3x+9y = -18 ...(***)
add (*) and (***) : 4y= -8 so: x = -2
