Why Does Current Lead Voltage by 110 Degrees in This Circuit?

[Edwardo_Elric]

Urgent question but simple problem:Phase difference

Homework Statement

What is the phase relationship between voltage and current?
i = 5sin(wt+30)
V = 10sin(wt+140)

Homework Equations

The Attempt at a Solution

it seems that drawing using cartesian, the voltage is leading the current by 110 degrees

but the correct answer is i leads v by 110 degrees why is that?
i thought the arrow with higher angle leads the lower angle

 

[Edwardo_Elric]

is it because the maximum limit of 90 degress phase difference is exceeded?

another example:
V = 2sin(wt+10)
i = sin(wt+210)

voltage leads current by 200 degrees?
