The distributive property.
Answer:
C 1/2
Step-by-step explanation:
It is an infinite solution. It is this because if you subtract 12x on both sides, you get 8=8, causing an infinite solution equation.
The correct answer is 13.86.
In order to find this, we must first note that the tangent of any angle is equal to the opposite side length over the adjacent side length. If we use that formula and the 60 degree angle, we can find y.
Tan(angle) = Opp/Adj
Tan(60) = y/8
8Tan(60) = y
13.86 = y
