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°

Inga [223]

Answer:

Step-by-step explanation:

16 ounces is equal to 1 pound

Divide 54 by 16 and you get 3.375

You know that there are 3 pounds now, so subtract 3 from what you got to get 0.375

Now multiply 0.375 by 16 to turn it back into ounces, which is 6
