Tolong Tentukan besar KLN ​

(3x + 15)° + (2x + 10)° = 180°

5x + 25 = 180°

5x = 180 – 25

5x = 155

x = 155/5

x = 31°

3x + 15

3(31) + 15 =

93 + 15 =

108°

Jawaban:

3x + 15 + 2x + 10 = 180°

5x + 25° = 180°

5x = 155°

x = 31

sudut KLN?

KLN = 3x + 15°

KLN = 3(31)° + 15°

KLN = 93° + 15°

KLN = 108°
