Determine the ordered pair that represents the coordinates of the point where the terminal side of the angle measuring 245∘ inte

The point
$x = \sin \theta \: and \: y = cos \theta$
lies on the unit circle.

The reference angle for 245° is 65°.

Since 245° lies in the third quadrant,

cosine is negative and sine is negative

Therefore 245° intersect the unit circle at

$x = - \sin ( 65 \degree ) \: and \: y = - \cos(65 \degree)$
In terms of x and y, 245° intersects the unit circle at

$( - x,-y)$
