Pada gambar berikut, hitunglah:a.Nilai xb.Besar KLNc Besar MLN#bantujawab​

Jawaban:

sudut kln = (3x+15)°

sudut mln = (2x+10)°

sudut kln + sudut mln = 180°

(3x+15)°+(2x+10)°=180°

(5x+25)° = 180°

(5x)° = (180-25)°

(5x)° = 155°

a. x = 155°/5° = 31

sudut kln = (3x+15)°= (3.31+15)° = (93+15)° = 108°

sudut mln = (2x+10)° = (2.31+10)° = (62+10)° = 72°

Jawaban:

a. Nilai x

(3x + 15)° + (2x + 10)° = 180°

3x + 2x + 15 + 10 = 180°

5x + 25 = 180°

5x = 155°

x = 31

b. Besar sudut KLN

(3x + 15) = 3(31) + 15

= 93 + 15

= 108°

c. Besar sudut MLN

(2x + 10) = 2(31) + 10

= 62 + 10

= 72°

bisa dikoreksi lagi

semoga membantu;)
