Well since an acute angle is everything with a smaller degree than a right angle, there is no perfect acute angle. However, to demonstrate an acute angle, i would go with around a 20-25 degree angle.
Any triangle with a 90 degree angle is a right triangle.
the best angle is "45 degree" because the air speed coming out of the fan is giving by this equation V=v.tanθ were : V: air speed,,, v: is the blades speed and we got the maximum of the speed by making the angle 45
It will have two 45 degree angles and one 90 degree angle with two of its three sides being equal in length.

I found a picture of a martini glass, and doing my best to measure the angle from the picture on the monitor, it looks like the bottom angle is about 70°, and the angle between the top edge and horizontal is about 55°. So that one would not be an obtuse angle. See related link.
The [horizontal] range of a projectile is maximised when it shoots at a 45 degree angle. This is true if air resistance is ignored so that the only force acting on the projectile is gravity.
The critical angle depends on the index of refraction of the two substances, in this case, air and glass. The angle can be calculated by Snell's Law. It won't always be exactly 39.3°, since different glasses have different indices of refraction.

At a 45 degree angle
In the first week of March. if you want it to grow it fast put plastic wrap or glass over top of it to perform a greenhouse effect or the colder days and at night.
