I need some help pleaseee

x=18

Step-by-step explanation:

Triangles add up to 180°, so 140+22+x=180 and then you simplify which is 162+x=180, then you subtract 162 on both side, getting x=18

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
