Given that the angle ABC is equal to the angle def, AB is equal to 3, AC is equal to 5, if the perimeter of the angle DEF is even, what is the length of ef?
Angle ABC is equal to angle def, wrong number. It should be, ⊿ ABC is equal to ⊿ def
If de = 3.df = 5, let EF = x, then x + 3 + 5 is even. X is also even. 2 < x < 8
X is 4 or 6
