Tolong di jawab gaes

Penjelasan dengan langkah-langkah:

sudut berpelurus

2x + 3x + 40 = 180

5x = 140

x = 28

maka

<MLN = 3x + 40

= 3(28) + 40

= 124°

Jawaban:

D. 124

Penjelasan dengan langkah-langkah:

${180}^{0} = {2x}^{0} + {3x}^{0} + {40}^{0} \ {180}^{0} = {5x}^{0} + {40}^{0} \ {5x}^{0} = { 180}^{0} - {40}^{0} \ {x}^{0} = {28}^{0}$

dicari besar sudut<MLN

${3x}^{0} + {40}^{0} \ = 3( {28}^{0}) + {40}^{0} \ = {84}^{0} + {40}^{0} = {124}^{0}$
