Given sin(u) = negative startfraction 7 over 25 endfraction and cos(v) = negative four-fifths, what is the exact value of cos(u-v) if both angles are in quadrant iii?
O negative startfraction 117 over 125 endfraction
O negative startfraction 24 over 25 endfraction
O three-fifths startfraction 117 over 125 endfraction
