    Answer:

    hope it was helpful

    Step-by-step explanation:

    tan 65 – tan 40 = tan 25 + tan 40 . using tanA – tan B =sin(A – B)/cosAcosB and tanA + tan B = sin( A + B)/cosAcosB we get :: to prove sin 25/ cos 65 = sin 65 / cos 25 sin 25 = cos (90 – 25) = cos 65 and sin 65 = cos (90 – 65) = cos 25
