alpha +beta=pie/2 & beta+gama=alpha then tan alpha=?

  • MATHEMATICS - ,

    let alpha = a
    beta = b
    gamma = g , for easier typing

    Since a+b = π/2 or 90°
    a , b and g can be assigned values in many ways

    e.g.
    a = 50°, b=40°, and g=10° , then we need tan 50°
    a = 70° , b = 20°, and g=50°, then we need tan 70°

    So tan a cannot be uniquely determined , and I think the question is bogus.
    Check your typing.
