Tolong banget jawabin skrang ntik di ksik poin bnyak​

Jawab:

a. 2x + x = 180°

   3x = 180°

    x = 60°

b.  2x + 40° + 34° = 180°

    2x + 40° = 180° – 34°

    2x = 146° – 40°

    2x = 106°

      x = 53°

c.  30° + 2x + 60° = 180°

    2x = (180°- 60°)-30°

    2x = 120° – 30°

    2x = 90°

      x = 45°

d. 3x + 2x + x = 90°

    6x = 90°

      x = 15°
