    cos 𝜽  = adj / hyp

    cos 𝜽 = 5/13

    adj = 5

    hyp = 13

    Like a right triangle

    adj² + opp² = hyp²

    5² + opp² = 13² 

    opp² = 169 - 25 = 144

    opp = 12

    Therefor

    adj = 5

    opp = 12

    hyp = 13

    -------------------------

    sin 𝜽 = opp/hyp = 12/13

    tan 𝜽 = opp/adj = 12/5

    sec 𝜽 = hyp/adj = 13/5

    csc 𝜽 = hyp/opp = 13/12

    cot 𝜽 = adj/opp = 5/12
