From the question,
We have the figure below
We are to find measure of angle 4
This will be done by following rule of corresponding angle
From the figure above
Angle 4 corresponds to to angle 42 degrees
And
Correspoinding angles are equal
Hence,
![\angle4=42^(\circ)](https://img.qammunity.org/2023/formulas/mathematics/college/juvbmn0c5abuo1u1rhgpwczimqbwkxsma0.png)
Therefore, measure of angle 4 is 42 degrees
