    sin A = opp/hyp = 5/13

    cos A = adj/hyp = 12/13

    tan A = opp/adj = 5/12

    sin A = opp/hyp = 2/(2√5) = 1/√5 = √5/5cos A = adj/hyp  = 4/(2√5) = 2/√5 = 2√5/5tan A = opp/adj = 2/4 = 1/2

    SinA = BC/AB = 5/13

    CosA = AC/AB = 12/13

    TanA = BC/AC = 5/12

    I shall leave you to do 9,10, and 11, otherwise you will not learn about Trig. Ratios.
