tolong dongg plis, beserta caranya
3b = ( 105° - 3a ) = 180°
3b = 180° - 30°
3b = 150°
b = 150°/ 3
b = 50°
Jadi 50° + 25° = D. 75°.

Menentukan nilai a
105° + 3a° = 180°
3a° = 180° - 105°
3a° = 75°
a = 75°/3
a = 25°
...
Menentukan nilai b
105° + 3b° = 180°
3b° = 180° - 105°
3b° = 75°
b = 75°/3
b = 25°
......
Maka,
a + b
= 25° + 25°
=50°
