    Applying the Laws of Sines or Cosines

    Solve the triangle.

    B = 36, a = 41, c = 17

    choices are

    b ≈ 29, C ≈ 20, A ≈ 124
    b ≈ 44, C ≈ 20, A ≈ 124
    b ≈ 29, C ≈ 121, A ≈ 23
    b ≈ 44, C ≈ 24, A ≈ 120

    Re: Applying the Laws of Sines or Cosines

    These look like test questions..

    So all I will put is this:

    b^2 = a^2 + c^2 - 2acCos(B)

    Where angle B is opposite side b
