Supplementary angles add up to 180 degrees. If \( m∠k = 117° \), you can find \( m∠j \) by subtracting \( m∠k \) from 180°:
\[ m∠j = 180° - m∠k \]
Substituting the value of \( m∠k \):
\[ m∠j = 180° - 117° = 63° \]
Therefore, \( m∠j = 63° \).
Angles j and k are supplementary angles. What is m∠j if m∠k=117° ?(1 point)
