Angles j and k are supplementary angles. What is m∠j if m∠k=117

Answer 1

If angles j and k are supplementary, then the sum of their measures is 180 degrees. Since m∠k = 117, we have:

m∠j + m∠k = 180

m∠j + 117 = 180

Subtracting 117 from both sides, we get:

m∠j = 180 - 117

m∠j = 63

Therefore, m∠j is 63 degrees.
