Answer:
the answer is B (5 square root 2, 315°), (-5 square root 2, 135°)
Step-by-step explanation:
1) Let A be the point (x, y) = (5, - 5)
=> x = 5 and y = - 5
r = √(x² + y²) = √(25 + 25) = √50 = ± 5√2
tan Θ = - 5/5 = - 1
=> Θ = (i) 315º or - 45º ; (ii) 135º or - 225
Hence, the Polar Coordinates of A are (i) (5√2, 315º) (ii) (- 5√2, 135º)
