5 is the correct answer.
To prove it, subtract 5 from 18 - You'll get 13.
5 x 2 + 3 = 13.
Answer:
(0, 1)
Step-by-step explanation:
The angle (1/2)π radians is equivalent to 90°. Since angles are measured counterclockwise from the +x axis, an angle of 90° (or π/2 radians) is in the direction of the +y axis.
Your polar coordinates of 1∠(π/2) specify a point 1 unit up from the origin on the y-axis. The coordinates of that point are (x, y) = (0, 1).
13.36 I don’t know if you need the rounded up form but if so 13.37
