To convert from rectangular coordinate (x, y) to polar coordinate (r, θ).
r is given by the square root of the sum of the squares of the rectangular coordinate.

and θ is given by the arctan of the ratio of y to x.

Example:
To convert rectangular coordinate (3, 4) to polar coordinate

Therefore, rectangular coordinate (3, 4) = polar coordinate (5, 53.13°)
it is 120 or the second one
Step-by-step explanation:
Multiplication
The rational number between 9.5 and 12 is
(9.5+12)/2 = 21.5/2 = 10.75
The answer is 8 units. Hope this helps:)
