___________________________________________

Cari Nilai x :

2x° + 3° + 75° = 180°

2x° = 180° - 3° - 75°

2x° = 180° - 78°

2x° = 102°

x° = 102° ÷ 2

x° = 51°

___________________________________________ Cari Nilai y :

3y° - 5° + 140° = 180°

3y° = 180° + 5° - 140°

3y° = 180° - 135°

3y° = 45°

y° = 45° ÷ 3

y° = 15°

___________________________________________ x - 2y

= 51° - 2(15°)

= 51° - (2 × 15°)

= 51° - 30°

= 21°

Opsi(B.)

___________________________________________ ${\mathcal\color{purple}{{\pink{\underline{\purple{\underline\bold{\pink{K}\bold\color{violet}{h\bold{\pink{a}\bold\color{violet}{d\bold{\pink{i}\bold\color{violet}{j\bold{\pink{a}\bold\color{violet}{h\bold{\pink{A}\bold\color{violet}{m\bold{\pink{j}\bold\color{violet}{a\bold{\pink{d}\bold\color{violet}{1\bold{\pink{2}}}}}}}}}}}}}}}}}}}}}}$

240° + 3y - 5° = 180°

135° + 3y = 180°

3y = 180° - 135°

3y = 45°

y = 45°/3

y = 15°

$\:$

75° + 2x + 3° = 180°

78° + 2x = 180°

2x = 180° - 78°

2x = 102°

x = 102°/2

x = 51°

$\:$

Maka:

x - 2y

= 51° - 2(15°)

= 51° - 30°

= 21°
