Answer:
x = 8, y = 4
Step-by-step explanation:
x = 3y-4
2x - 8 = 2y
x - 4 = y
x = y + 4
substitute top equation to this equation
3y-4 = y+4
2y = 8
y = 4
now substitute this into second equation
x = y + 4
x = 8
check answer with first equation
x = 3y-4
8 = 3(4) - 4
8 = 8; correct
The total of the internal angles in a tetradecagon is 2160.
2160 - 2012 = 148
The remaining angle must be 148 degrees.
X = 14
Add them all together and set them equal to 180 then solve for x
The equation is separable, so solving it is trivial:
Integrating both sides gives
Given 
and 
, we find
so the answer is E.
It will take 9 hours but will you trust me?
