\angle E=39

Step-by-step explanation

Step 1

the angle y is congruent to angle 119, so


\angle y=119\text{ \degree}

angle G and angle Y are vertical angles(Vertical angles are angles opposite each other where two lines cross.) and those angles are congruent

so


\begin{gathered} \angle y=119 \\ \angle G=\angle y \\ \angle G=119 \end{gathered}

Step 1

finally, the sum of the internal angles in a triangle equals 180, so


\begin{gathered} \angle B+\angle G+\angle E=180 \\ replace \\ 22+119+\angle E=180 \\ 141+\angle E=180 \\ \text{subtract 141 in both sides} \\ 141+\angle E-141=180-141 \\ \angle E=39 \end{gathered}

so, the answer is


m\angle E=39

I hope this helps you
