Question

What is the measure of ∠KMN?

A. 29 degrees
B. 66 degrees
C. 53 degrees
D. 89 degrees

Answer 1

B) 66

Explanation:

75+39=114

180-114=66

Answer 2

∠KMN = 66°

Explanation:

In ΔKMN,

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

39 + 75 + ∠KMN = 180

114 + ∠KMN = 180

∠KMN = 180 - 114

∠KMN = 66°
