What is the measure of /x? Angles are not necessarily drawn to scale.
PLS HELP I REALLY NEED TO GET THIS RIGHT!!

x = 66°

Step-by-step explanation:

First, you can use exterior angle theorem to say that

and you can substitute to get:

105° = 39° + m<DJI

m<DJI = 66°

m<DJI and m<AJF are vertical angles, so they equal each other:

m<DJI = m<AJF

m<AJF = x = 66°
