tolong yang jago matematika nomer 2

Semoga dapat membantu

2.) a.)

[tex]120 + 60 + 2x + x = 360 \\ 180 + 3x = 360 \\ 3x = 360 - 180 \\ 3x = 180 \\ x = \frac{180}{3} \\ x = 60[/tex]

Jadi, nilai x = 60°

2.) b.)

[tex]PTS = \frac{1}{2} \times (POS-QOR) \\ PTS = \frac{1}{2} \times (2x-x) \\ PTS = \frac{1}{2} \times x \\ PTS = \frac{1}{2} \times 60\\ PTS = 30[/tex]

Jadi, besar PTS = 30°
