Penjelasan dengan langkah-langkah:

<ABE + <EBC = 180°

3x+10 + 2x–20 = 180°

5x – 10 = 180°

5x = 10 + 180

5x = 190

x = 190/5

x = 38°

<ABE = 3×38+10 = 124°

<EBC = 2×38–20 = 56°

Penjelasan dengan langkah-langkah:

3x + 10 + 2x - 20 + 60 = 180

3x + 2x + 10 - 20 + 60 = 180

5x + -20 + 60 = 180

5x + 40 = 180

5x = 180 - 40

5x = 140

x = 140/5

x = 28

ABE

3x + 10

3(28) + 10

84 + 10

94°

EBC

2x - 20

2(28) - 20

56 - 20

36°
