the acute angles of a rhombus are 76 degrees if the shorter diagonal is of length 8 cm calculate of the sides of the rhombus to the nearest mm

Ms Sue pls help
the diagonals of a rhombus right-bisect each other, so
make a sketch and look at the right-angled triangle with angle 38° (half the 76) and leg of 4 cm
The hypotenuse is the side of the rhombus, call it x
sin 38° = 4/x
x = 4/sin38 = appr. 6.487 cm
= appr 65 mm
