  1. To avoid confusion, the sides of the
    triangle should use lower case letters:

    A = B+C
    a = 5
    b = 4
    c = 3

    Angle between a and c = ?

    We have a 3-4-5 rt. triangle.
    A = B+C = 90o

    The longest side is always opposite the
    largest angle:
    a = hyp. = 5 Units.
    b = 4 Units.
    c = 3 Units.

    Tan B = b/c = 4/3 = 1.33333
    B = 53.13o = Angle between a and c.
