need some angles please

[devonwoody]

A neighbour as asked me to make four flower boxes triangular in shape to fit a plinth and form a star pattern to a font at her church as per drawing below.

Could someone please tell me the angle at the apex to join the two long sides.

the back length I thought could have a flat finish and the two long sides angled to join inside the 12" board.

Making in 10mm mdf and butt jointing all joints with titebond 3

Hi

I'm not sure MDF will be suitable if it's liable to get wet.

I think it is only a one off for Easter decoration.
