sudut KLN (3x+15)° dan sudut MLN (2x+10)°. besar susdut KLN adalah...

Kalau gambarnya garis lurus berarti 180

(3x + 15)° + (2x + 10)° = 180
3x + 2x + 15 + 10 = 180
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 155/5
x = 31

KLN = (3x + 15)° = 3(31) + 15 = 93 + 15 = 108°

KLN = 108°

Maaf kalau salah

(2×+10)(3×+15)
(2×+10)+(3×+15)=180
6×+25=180
5×=180-25
×=155
×=31

2×+10=
2.31+10= 62+10=72

maaf kalau salah ..
