Answer 1

Supplementary angles are two angles whose measures add up to 180 degrees.

Given that \( m∠k = 117° \), we can find \( m∠j \) using the formula:

\[
m∠j + m∠k = 180°
\]

Substituting the value of \( m∠k \):

\[
m∠j + 117° = 180°
\]

To find \( m∠j \), subtract 117° from both sides:

\[
m∠j = 180° - 117°
\]
\[
m∠j = 63°
\]

Therefore, \( m∠j = 63° \).
