Jawaban:
15. A
16. C
17. C
Penjelasan dengan langkah-langkah:
15. Penyiku = pembuat 90°
25° + (4x-15)° = 90°
4x + 10° = 90°
4x = 90-10°
x = 80°/4
x = 20°
16. 120° + x = 180° (karena sudut lurus)
x = 180° - 120° = 60°
17. (2x+8)° + 110° = 180°
(2x + 8)° = 180° - 110°
2x + 8° = 70°
2x = 70° - 8°
2x = 62°
x = 62°/2 = 31°
