Identify the quadrant in which the angle lies.



929° lies

1 answer

To find the quadrant in which the angle \( 929^\circ \) lies, we first need to reduce the angle to an equivalent angle within the interval \( [0^\circ, 360^\circ) \). We can do this by subtracting multiples of \( 360^\circ \) from \( 929^\circ \).

Calculating:

\[ 929^\circ - 360^\circ \times 2 = 929^\circ - 720^\circ = 209^\circ \]

Now, \( 209^\circ \) is the angle we'll analyze.

Next, we determine in which quadrant \( 209^\circ \) lies:

  • \( 0^\circ \) to \( 90^\circ \): Quadrant I
  • \( 90^\circ \) to \( 180^\circ \): Quadrant II
  • \( 180^\circ \) to \( 270^\circ \): Quadrant III
  • \( 270^\circ \) to \( 360^\circ \): Quadrant IV

Since \( 209^\circ \) is between \( 180^\circ \) and \( 270^\circ \), it lies in Quadrant III.
