(PED or E D) is the formula for this answer
Answer:
x = 100°
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, hence
sum = 180° × 5 = 900°
Sum the given interior angles and equate to 900
x + 155 + 116 + 135 + 135 + 116 + 143 = 900
x + 800 = 900 ( subtract 800 from both sides )
x = 100°
Answer:
6.71
Step-by-step explanation:
c=
(3-9)^2+(-1+4)^2
c=√36+9

The fourth one Its tell you to add or miners or multiple
Step-by-step explanation:
And then the rest is telling you to explain you answer using your own words.
The algebraic equation is 4(0.25)+2x=17
STEP 1: Simplify both sides of the equation
1+2x=17 or 2x+1
STEP 2: Subtract both sides
2x = 16
STEP 3: Divide both sides by 2
2x/2 = 16/2
x = 8
