Establish the identity tan (37 + 0) = tan O. Which of the following four statements establishes the identity? OA. tan 31t + tan tan (31 + ) = 1 + tan 31 tane 0 + tan e = tan 1 +0. tano ОВ. tan 31t - tan 0 tan (34 + 0) = 1 - tan 3 tane 1 -- tan tan 1-(1). tane OC. --- tan 311 - tan 0 tan (34 + ) = 1 + tan 31 tane 1 + tan o 1 + 1 . tan tan OD. tan 3, + tan o tan (31 + 0) = 1 - tan 3 tan 0 0 + tan e 1-0. tan tan e
