Answer:
23 sides
Step-by-step explanation:
The sum S of the interior angles of an n sided polygon is given as
S = (n - 2)180°
Where S is the sum of the interior angles and n is the number of sides.
Given that the sum of the interior angles is 3780° then
3780° = (n - 2)180
Divide both sides of the equation by 180
21 = n - 2
n = 21 + 2
= 23
The polygon has 23 sides
Hey there! I'm happy to help!
We have two values for y in terms of x. We can now create an equation to solve for what x is.
-4x+2=-x-1
We add x to both sides
-3x+2=-1
We subtract 2 from both sides.
-3x=-3
We divide both sides by -3.
x=1
Now, we can plug our x into one of the original equations and then solve for y!
y= -4+2
y=-2
We can also test this with the other.
y= -1-1
y=-2
Therefore, our solution is (1, -2), or x=1 and y=-2.
I hope that this helps!
