If 180° ≤ x ≤ 270°, then x =

x = 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, ..., 260, 261, 262, 263, 264, 265, 266, 267, 268, 269, 270.

Step-by-step explanation:

≤ means less than or equal to, so it means 180 is less than or equal to x

and x is less than or equal to 270.

x = 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, ..., 260, 261, 262, 263, 264, 265, 266, 267, 268, 269, 270.

Nothing further can be done.
