The sum of \(3a + 3b = 360\)
1) Plugging in \(a = 35\) into \(3a + 3b = 360\)
\(3(35) + 3b = 360\)
\(105 + 3b = 360\)
\(3b = 255\)
\(b = 85\)
b>a
SUFFICIENT
2) If a = 60 then plugging that into \(3a + 3b = 360\) would give us that b = 60, and that a=b. However, as we know that a<60, then automatically b>a.

Nowhere in the question suggests that all the lines are passing through one singular point, additionally the prompt says that the figure is not drawn to scale, which suggests that we cannot just assume that the lines are passing through one point. I think this question has issues. Please let me know if i am thinking right?Bunuel
