Find Length of Segment AB in Circle Co-ordinate Question

[anmolnanda]

the question:
if a straight line c(-*8^1/2,-*8^1/2) making an angle 135 dge with x-axis,cuts the circle x=5cosm y=5sinm in points A and B ,find length of segment AB .
in the equation of line by solving i got y=-x
and tried to solve and ended up getting length of AB as 0 but the solution has done a different way and got different answer//probably i am using some wrong concepts..please help

hi anmolnanda!

(have a square-root: √ and a degree: ° )

the question:
if a straight line c(-*8^1/2,-*8^1/2) making an angle 135 dge with x-axis,cuts the circle x=5cosm y=5sinm in points A and B ,find length of segment AB .

i don't understand …

what does that point have to do with it?

what exactly is the question?​
