rectangular coordinates: (6, -8)
ok i got r=10 which im pretty sure is right but im unsure about q.
q=tan-1(y/x)
so i got q= -53.13)
but i checked it on a conversion thing and it said q is like 307??? what did i do wrong

Hello tomatoesYour answer is OK, but if you need to give an angle between and , then you'll need to subtract from , which is where the comes from.
There are two values of in the range for which . They are (to the nearest degree) and . Since is in the fourth quadrant, the answer you want is .
