The shorter diagonal of a rhombus is 10 inches long, and the angle the
diagonal forms with the side measures 60º. Find the area of the
rhombus.

I really don't know where to start. I know that the area formula for a
rhombus is
A=1/2*d1*d2
So if I know that one of the D is 10, how do i get the area? I don't know
where the angle measurement is very helpful either.

Help?

Draw the picture.

The angle helps a lot. You know the diagonal bisects that corner angle, so now you know the corner angles. If you know the corner angles, you know the central angles. With these, you can determine the lengths of all parts of the figure.

Repost if you need more help.

Isn't the central angle 90 because the diagonals intersect? How do I find the 2nd diagonal?
