Angles j and k are supplementary angles. What is m∠j if m∠k=117° ?(1 point) °
If angles j and k are supplementary angles, it means that the sum of their measures is 180 degrees. Therefore, if the measure of angle k (m∠k) is 117 degrees, the measure of angle j (m∠j) can be calculated as follows:
m∠j = 180° - m∠k
m∠j = 180° - 117° = 63°
So, m∠j = 63°.
