Help me plz and thank you

x = 66 degrees, y = 57 degrees

Step-by-step explanation:

180 - 123 = 57 = y

57 + 57 + x = 180

114 + x = 180

x = 66

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.
