The conversion is
So
We're given the fairly unusual
It's fairly unusual because usually an angle is given in degrees or radians, and typically the radians are a fraction times pi. We'll assume radians.
Ah, there's our .75. The approximate answer is
Third choice.
The exact answer is
also a line through the origin.
