Determine two pairs of polar coordinates for the point (5, 5) with 0° ≤ θ < 360°.

a (5 square root 2, 225°), (-5 square root 2, 45°)

b (5 square root 2, 315°), (-5 square root 2, 135°)

c (5 square root 2, 135°), (-5 square root 2, 315°)

d (5 square root 2, 45°), (-5 square root 2, 225°)

 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)

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
