Answer:
x = 20
Step-by-step explanation:
(2 + 3x) and 62° are vertically opposite angles and are congruent, so
3x + 2 = 62 ( subtract 2 from both sides )
3x = 60 ( divide both sides by 3 )
x = 20

Functions are a set of points that show how dependent variables change through independent variables.
Defining a Function
In functions, each x-value is assigned to exactly one y-value. This means that x-values do not repeat. So, if there is one x-value more than once in a set, then it cannot be a function.
For example, set B has the x-value 3 and 4 repeated twice. Thus, it does not represent a function.
Graph of a Function
Functions can also be defined through a graph. Just like with coordinate points, x-values do not repeat on the graph. You can use the vertical line test to see if a graph is a function. If you can draw a vertical line at every point on a graph without it ever intersecting with the graph more than once, then it is a function.
