Question

What is the measure of ∠KMN? A. 29 degrees B. 66 degrees C. 53 degrees D. 89 degrees

Answer 1

Answer:

B) 66

Step-by-step explanation:

75+39=114

180-114=66

Answer 2

Answer:

  ∠KMN = 66°

Step-by-step explanation:

In ΔKMN,

∠MKN + ∠KNM + ∠KMN = 180       {Angle sum property of triangle}

39 + 75 + ∠KMN = 180

       114 + ∠KMN = 180

               ∠KMN = 180 - 114

           ∠KMN = 66°
