Answer:

x = 13

Step-by-step explanation:

110° is the vertically opposite angle of one of the interior angles of the given triangle.

Therefore,

$x \degree + 57 \degree + 110 \degree = 180 \degree \\ \\x \degree + 167 \degree = 180 \degree \\ \\ x \degree = 180 \degree -167 \degree \\ \\ x \degree = 13 \degree \\ \\ x = 13$

Graph should represent "miles per gallon" that means the y axis are miles driven with x axis gallons used.

See image attached.

The fuel usage is approximately linear so the graph is a line. The origin of the graph (0,0) corresponds to the starting point in MIami, FL, where 0 gallon have been spent and 0 miles driven. the endpoint corresponds to Atlanta, GA, where 90 gallons have been spent and 660 miles driven. The domain is real numbers in the interval [0,90]. The x intercept is 0, the y intercept is also 0. The range is real numbers in the interval [0,660].
