Determine the angle in standard position whose terminal arm connects to the given point, (-6, -13). 0 ≤ Θ ≤ 2π (Round off to 4 decimal places.)

Answer 1

tanx = -13/-6 = 13/6 use a calculator with an inverse trig function

x = 65.2249 degrees + 180 = 245.2249 degrees

It's in the 3rd quadrant, so add 180
