If a right angle measures 90 degrees how much does a acute measure

At least zero and less than 90 degrees

Step-by-step explanation:

The angles of a triangle are classified as ...

acute - - less than 90° right - - exactly 90° obtuse - - greater than 90°

If x is the measure of an angle and ...

0 ≤ x < 90°

then the angle is an acute angle.

Less than 90 degrees and at least zero.

Step-by-step explanation:

If a right angle measures 90 degrees, an acute measures less than 90 degrees and at least zero.
