2x-438 = -438+2x= 2(x-219)
Well, if that is a comma in the number, it is already rounded. If the comma is supposed to be a decimal, the answer would be $57.
<span>Based on the problems I have recently done on FLVs with this though, is that if you connect the center of the arcs to the top intersection point, if the angle degrees, and opposite arcs are the same then it is an equilateral triangle.</span>
Answer:
s = 1
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 = 5 , then
sum = 180° × 3 = 540°
sum the interior angles and equate to 540
39s + 129 + 79 + 145 + 148 = 540 , that is
39s + 501 = 540 ( subtract 501 from both sides )
39s = 39 ( divide both sides by 39 )
s = 1
