Hello,
- 3&2/5=-17/5=-3.4
==>-3.4<n<-2.7
==>n=-3 (if -3 is an integer)
I think it might be c or A
5/13
The x value is negative (second quadrant). 13 is the hypotenuse. So the missing side is 13^2 = (-12)^2 + y^2.
Sin theta is the opposite (5) over hypotenuse (13).
Yes you are correct very nice job!
