Classify the marked angle pair,give their relationship,and solve for x

The measure of x is 12
Here, we want to classify the realationship between the two marked angles
From what we have, the two angles are equal
The reason for this is that they are corresponding angles; and corresponding angles are congruent (equal)
Thus, mathematically;
[tex]\begin{gathered} 5x-2\text{ = 58} \\ \\ 5x\text{ = 58+2} \\ \\ 5x\text{ = 60} \\ \\ x\text{ = }\frac{60}{5} \\ \\ x\text{ = 12} \end{gathered}[/tex]
