Answer:

Cosine Formula :

AC² = AB² + BC² - 2(AB)(BC)cosB

AC² = (40)² + (60)² - 2(40)(60)cos(115°)

AC² = 1600 + 3600 - (4800×(-0.42))

AC² = 5200 + 2016

AC² = 7216

AC = √(7216)

AC = 84.95 km

Hence, the distance of the straight line AC is 84.95 km

  • 84.95km is the right answer.

Hope you could understand.
