Answer:

f = 52°

Explanation:

the 2 angles are adjacent and therefore supplementary, thus

f + 128° = 180° ( subtract 128° from both sides )

f = 52°

Answer:

f=52 degrees

Explanation:

If I see the problem correctly the other number is 128 if so then you can use the DLD thm. That says 180=angle+angle in a linear pair. So that means that here it's 180=128+f. Substract 128 from each side to get x alone and that gets you f=52. (Angle is degree so add degree sign)
