Morphology
The meaning is directly compositional: 'acute' (meaning sharp/small) modifies 'angle' so it denotes a relatively small angle (less than 90°). This is a standard, cross-linguistically similar mathematical term, so a B1 learner who knows both constituents can reliably infer the MWE meaning.
Etymology
Acute angle may come from an old word meaning 'sharp' or 'pointed'. The word acute describes a small, sharp corner of an angle. So an acute angle is one that is less than 90 degrees.
