I need d and e. Have a right triangle. Base=d; hypotenuse=e; altitude= 2sqrt3. < opposite 90 = 60.

there is no angle opposite the right angle.

However, the sides in this triangle are in the ratio 1:√3:2

So, if d is opposite the 60° angle, it is the long side, and the sides are 2, 2√3, 4

If d is opposite the 30° angle, it is the short side, so the sides are 2√3, 6, 4√3
