X=15degrees
The angle measurements are 30, 30, and 120 so it is an isosceles
We have the equation:

Given the slope-intercept formula for the equation of the line, we have the following:

Now, since we have that t is the number of hours the electrician spends working, the slope of the function represents the hourly rate charged.
