The answer is 2/5 < 1/2
Because if you do common denominator which is 10 you get 2/5 as 4/10 and 1/2 as 5/10 so therefore 1/2 is greater
Sure, in a second. still needed?
12x+10y=38
If it doesn't give you any measurements than I would say x degrees

Answer:
∠ FAB = 75°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ FAB is an external angle, thus
13x - 3 = 3x + 2 + 55 = 3x + 57 ( subtract 3x from both sides )
10x - 3 = 57 ( add 3 to both sides )
10x = 60 ( divide both sides by 10 )
x = 6
Thus
∠ FAB = 13x - 3 = 13(6) - 3 = 78 - 3 = 75°
