we know that
the sum of the internal angles of a triangle is 180 degrees
so
in this problem
(10x−2)=128∘--------->; 10x=128+2---------> 10x=130------>; x=130/10
x=13°
the angles are
13°, 13°
and
the third angle is equal to
180-2*(13)=154°

the answer is
the measurement of one of the acute angles is 13 degrees
