Step-by-step explanation:

Acute angles can't be over 90°

The measure of the other acute angle is 59 degrees

The mistake the student has made is subtracting 31 degrees from 180 degrees (the total amount of degrees a triangle has)

The student needed to realize
A) acute angles are less than 80 degrees
B) he needed to subtract 90 from 180 as well.

180 - 90 (from the right triangle) - 31 = 59
