Answer:
x = 111
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 7 , then
sum = 180° × 5 = 900
Sum the interior angles and equate to 900
x + 139 + 121 + 125 + 126 + 158 + 120 = 900
x + 789 = 900 ( subtract 789 from both sides )
x = 111
Answer:
area = 6x^2+10x-4 perimeter= 5x+3
Step-by-step explanation:
1, 3, 9 and -1, -3, and -9 i guess

21 because a triangle is always going to equal 180 so add those then subtract and it’s 21
