If the m∠A is less than 90°, then ∠A is an acute angle. M∠A=75° . What can you logically conclude using the Law of Detachment? ∠A is acute. ∠A is acute. ∠A is right. ∠A is right. ∠A is obtuse. ∠A is obtuse. Not enough information. Not enough information.

∠A is acute. ∠A is acute.

Step-by-step explanation:

Given that

m∠A is lower than 90°

So, it is an acute angle

And, M∠A=75°

The acute angle is the angle that measures between 0 degrees and 90 degrees on the other case the obtuse angle should be more than 90 degrees till 180 degrees

So as per the law of detachment the first option is correct and the same is to be considered
