if the diagonals of a rhombus is 12 and 16 what is the measure of a side of the rhombus 5,,20,10 square root 3

The diagonals of a rhombus intersect at right angles. So the two half diagonals and one side form a right triangle, with lengths: (12/2)=6, (16/2)=8,
What is the length of a side (hypotenuse).
Hint: use Pythagoras theorem.
