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
