Answer:

The value of x is 5 degree;


x=5

Step-by-step explanation:

From the diagram attached, line EF bisects angle DEG.

So;


\measuredangle DEF=\measuredangle FEG

Given;


\begin{gathered} \measuredangle DEF=6x-3 \\ \measuredangle FEG=4x+7 \end{gathered}

Substituting and solving;


\begin{gathered} 6x-3=4x+7 \\ \text{add 3 to both sides;} \\ 6x-3+3=4x+7+3 \\ 6x=4x+10 \\ \text{subtract 4x from both sides;} \\ 6x-4x=4x-4x+10 \\ 2x=10 \\ \text{divide both sides by 2;} \\ (2x)/(2)=(10)/(2) \\ x=5 \end{gathered}

Therefore, the value of x is 5 degree;


x=5
