A rhombus has a diagonals of length 4 and 10. Find the angles of the rhombus to the nearest degree.

In a rhombus the diagonals rightbisect each other, so you would have 4 identical rightangled triangles.
The sides of one of these would be 2 and 5.
I would use the tangent to find one of the acute angles.
