In this image, we see two intersecting lines with numbered angles. Since ∠5 is adjacent to ∠47° and both angles form a straight line, they are supplementary.

To find \( m∠5 \), we use the property of supplementary angles:

\[
m∠5 + 47° = 180°
\]

Thus,

\[
m∠5 = 180° - 47° = 133°
\]

So, \( m∠5 = 133° \).
