If sin theta = -2/3 which of the following are possible fore the same value of theta? cos theta = square root 5 / 3 and tan theta = 2 / square root 5
sec theta = 3 / square root 5 and tan = -2/ square root 5
sec theta = -3 / 2 and tan theta = 2 / square root 5
cos theta = -square root 5 /3 and tan theta = 2 / square root 5
