The line is the same in all answers, so you may look at the inequality signs. The shaded area is on top, this means greater than, and the line is not dashed, so it belongs to the solution: greater or equal than
Answer:
40 degrees
Step-by-step explanation:
2x + 3x + 2x + x + 10 + 30 = 360
Combine like terms
8x + 40 = 360
8x = 360 - 40
8x = 320
x = 320/8
x = 40
40 degrees
