Answer:
183.6 miles
Step-by-step explanation:
Kindly check the picture attached for the solution diagram
Using the cosine formula (Diagram has two sides and an included angle)
x² = y² + z² - 2zy * cosX
x² = 150² + 60² - 2(150*60) * cos115
x² = 22500 + 3600 - 18000 * −0.422618
x² = 22500 + 3600 + 7607.1287
x² = 33707.128 miles
x = √33707.128
x = 183.59501
x = 183.6 miles
