The height BM, drawn from the vertex of the corner of the rhombus ABCD, forms an angle of 30 degrees with side AB, AM = 4 cm. K find the length of the diagonal BD of the rhombus if point M lies on side AD.
If am lies opposite a corner of 30 degrees
Therefore, it is equal to half of the hypotenuse ab: ab = 2am * 4 * 2 = 8, since ab = ad by the rhombus property.
So the answer is: 8
