X means everything in algebra. It is a variable, which means that its meaning changes based on context. For example, x could be time, but it could also be cars. x is what all Mathematicians chase after and it is also the greatest tool at their disposal. x is generally called an independent variable because its value determines the output of a function. y, on the other hand, is the result of fooling around with x. It's a dependent variable, which means that y changes when x changes.
Take, for instance, the following function:
y = x + 3
Let's set x = 3.
y = (3) + 3
y = 6
As you can see, what we input as x determines what y outputs.
Answer:
x is 4

Answer:
c = 0.5 cm
Step-by-step explanation:
Law of sines:
sin (15) / c = sin(105) / 2
0.2588 / c = 0.9659 / 2
c = 0.2588 * 2 / 0.9659
c = 0.5 cm
