Hi there! Natalie's age is 13 and Fred's age is 26
Let Natalie's age be represented by x.
Let Fred's age be represented by y.
The sum of Natalie's and Fred's age is 39, so x + y = 39
The sum of three times Natalie's and (one time) Fred's age is 65, so 3x + y = 65
Eliminate y by subtracting
Divide by -2
Subract 13
Therefore, Natalie's age is 13 and Fred's age is 26

Answer:
Angle ABF is 120°.
Step-by-step explanation:
Vertical angles are used to get the measure of angle ABG (3x) and FBE (2x) and all of those added together are 180. Then you use PEMDAS to get x. Then you find ABF by multiplying 3 by 30 (what you get when you use PEMDAS to find x) then you add 30 to that and you get 120.
