Angle ABC and angle EBF are a pair verical angles. The measurement of angle ABC = 3X + 8 and the measurement of angle EBF = 2X + 48. What are the measurements of angle ABC and angle EBF

Vertical angles are equal.
3x+8=2x+48
x=40 deg
so now you have x, put that in the expression for each angle (3x+8;2x+48) and you have the angles. 
Angle ABC = 128
Angle EBF = 128
