Angles j and k are supplementary angles. What is m∠j if m∠k=117° ?(1 point)
°
If angle k is 117° and angles j and k are supplementary, it means that the sum of angles j and k is 180°.
To find the measure of angle j, we need to subtract the measure of angle k from 180°.
m∠j = 180° - m∠k
m∠j = 180° - 117°
m∠j = 63°
