minus 2
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:
V= 628.32
Step-by-step explanation:
Ok so assuming the 0 means minus from typing problems
x^2-10x=-8
to completet the square
make sure the term in front of x^2 is 1
that is correct
then take 1/2 of the term in front of the x term and square it
-10/2=-5, (-5)^2=25
add that to both sides
x^2-10x+25=17
answer is the first equation
