Decide whether the statement is possible or impossible. tan 0 = -2 and cot0 = -2 Is the statement possible or impossible? O A. The statement is possible because tan 0 = coto. OB. The statement is impossible because tan 0 = - coto 1 O C. The statement is possible because tan 0 = cot 1 D. The statement is impossible because tan 0 = coto
