1212Use the trigonometric identity to solve for
, then use the Quadrant information to solve for
, which can then be used to find
and
.
Substitute the into the trigonometric identity:
, which becomes
, so
.
Evaluate the square root to find sin\u03B8:
. It is given that the cosine value is in Quadrant III, so the sine value is negative and equals
.
