Diagonal in a rhombus splits an angle in two, which means that this angle would be 140'. The sum of all angles equals 360' and two of those are 140'. 360'-280'=80' Then, the last thing you need to do is split it into two (as there are two acute angles and they are the same) which gives us 40'.

The answer is - The acute angle equals 40'.
