Question 958282
This problem cannot be solved without additional information. This is so because<ul><li>To find sin(x+y) we will use the identity:
sin(x+y) = sin(x)cos(y) + cos(x)sin(y)</li><li>The identity requires cos(x) and cos(y).</li><li>But without information telling us the quadrant in which x and y terminate, we cannot find these cos's.</li></ul>
