Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

1.

90° = 8x° + 10x° \\ 90° = 18x° \\ \frac{90}{18} = x \\ 5 = x

2.

180° = 5x° + 4x° + 9° \\ 180° = 9x° + 9° \\ 180° - 9° = 9x° \\ 171° = 9x° \\ \frac{171}{9} = x \\ 19 = x

3.

180° = 7x° + 5x° \\ 180° = 12x° \\ \frac{180}{12} = x \\ 15 = x

4.

90° = 2x° + 12° + x° + 33°\\ 90° = 3x° + 45° \\ 90° - 45° = 3x° \\ 45° = 3x° \\ \frac{45}{3} = x \\ 15 = x

5.

90° = 6x + 4 + 3x + 5 \\ 90 = 9x + 9 \\ 90 - 9 = 9x \\ 81 = 9x \\ \frac{81}{9} = x \\ 9 = x

6.

180 = 7x + 8 + 5x + 4 \\ 180 = 12x + 12 \\ 180 - 12 = 12x \\ 168 = 12x \\ \frac{168}{12} = x \\ 14 = x

7.

180 = 3x + 15 + 2x + 10 \\ 180 = 5x + 25 \\ 180 - 25 = 5x \\ 155 = 5x \\ \frac{155}{5} = x \\ 31 = x

8.

180 = 6x + 8x + 4x \\ 180 = 18x \\ \frac{180}{18} = x \\ 10 = x

maaf jika salah, semoga membantu
