The answer is

18(b)

AB² = 8² + 15² – 2 . 8 . 15cos70 AB = 14.4 ½ × 14.4 × CX = 56.4 56.4 x 2/14.4

so i dont think so

The answer is

AB² = 8² + 15² – 2 . 8 . 15cos70 AB = 14.4 ½ × 14.4 × CX = 56.4 56.4 x 2/14.4

so i dont think so

oh sorry I forgot about the answer, I have no idea then, I hated maths last year.
