The diagonals of a rhombus are 320mm and 240mm in length.Find the angles of the rhombus.

  • Maths -

    Since the diagonals of a rhombus are perpendicular, you have four right triangles, with sides 120-160-200.

    if the angles of the rhombus are A and B,

    tan A/2 = 3/4
    tan B/2 = 4/3

    evaluate and double, done.
