Angles j and k are supplementary angles. What is m∠k if m∠j=34°

Supplementary angles are two angles that add up to 180 degrees.

Given that m∠j = 34° and angles j and k are supplementary, we can set up the equation:

m∠j + m∠k = 180°

Substituting in the given value:

34° + m∠k = 180°

Subtracting 34° from both sides:

m∠k = 180° - 34°

m∠k = 146°

Therefore, m∠k is equal to 146°.
