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.
A right angle
To pour a perfect draught of beer, tilt the glass at a 45-degree angle and slowly pour the beer down the side of the glass. Gradually straighten the glass as it fills to create a nice head of foam. Serve immediately for the best taste.

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.
it is a try square

To cut a 45-degree angle on a piece of wood, the best way is to use a miter saw or a miter box with a handsaw. Measure and mark the angle on the wood, then position it securely in the saw or miter box. Carefully cut along the marked line to achieve a precise 45-degree angle. Remember to wear safety goggles and follow all safety precautions when using power tools.
To cut wood at a precise 45-degree angle using a miter saw, the best technique is to adjust the miter saw's angle to 45 degrees, secure the wood firmly against the fence, and make the cut slowly and steadily to ensure accuracy.
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.
The best techniques for cutting 45-degree angle brackets in wood include using a miter saw or a miter box with a handsaw. Measure and mark the angle accurately, secure the wood firmly, and make the cut slowly and steadily to ensure precision. Sand the edges for a smooth finish.
