Angles j and k are supplementary angles. What is m∠k if m∠j=117° ?(1 point)
If angles j and k are supplementary, it means that the sum of their measures is 180 degrees.
Given that m∠j = 117°, let's solve for m∠k.
m∠j + m∠k = 180°
117° + m∠k = 180°
Subtracting 117° from both sides we have:
m∠k = 180° - 117°
m∠k = 63°
Therefore, m∠k is 63°.
