A rhombus is your answer

A square if it has 4 equal angles too, or a rhombus if it has two obtuse and two acute angles.
A rhombus would fit the given description which has 2 equal opposite acute angles and 2 equal opposite obtuse angles whereas the 4 angles add up to 360 degrees.
Impossible.
I suggest you go back and check what you want. There is no such thing as an acute side. You cannot have 1 equal obtuse angle (equal to what?).
"z" has two acute angles a triangle can have 3 acute angles but also will have a angle >= 60degrees acute (also note for every acute angle a obtuse angle is formed the sum of the obtuse and acute angle will = 360) because of this a arrow is the only shape with two acute angles and 1 obtuse
A square
2 obtuse and 2 acute in the classic kite shape.
