Answer 1

Verified answer

Dua sudut luar berseberangan sama besar

[tex] Nilai \: x \\ 3x° - 25 °= 2x° + 25° \\ 3x° - 2x° = 25° + 25 °\\ x = 50° \\ \\ Besar \:pelurus \: sudut \: A \\3x° - 25° \\ 3(50°) - 25° \\ 150° - 25° \\ 125 °\\ \\ Besar \: sudut \: A \\ 180° - 125° \\ 55° \: (A)[/tex]

Answer 2

Materi : Garis dan Sudut , SPLSV

3x - 25 = 2x + 25

3x - 2x = 50

x = 50°

---

3x - 25 + A = 180°

150° - 25 + A = 180°

125° + A = 180°

A = 55°

Semoga bisa membantu
