Question

The measure of is MKN degrees.The solution is _________

Answer 1

From the diagram, we can see that the combination of angles JKM, MKN, and NKL make a straight angle, that is,

m∠JKM + m∠MKN + m∠NKL = 180°

Substituting with data:

60° + m∠MKN + 35° = 180°

m∠MKN = 180° - 60° - 35°

m∠MKN = 85°
