You know that Akiko is 45 miles from the origin...Kosuke is (135/4) miles from the origin... You can draw a figure to clearly see the situation.
<span>you "know" that the angle between their routes is 140º </span>
<span>the side opposite (140º) is the distance between them... </span>
<span>c^2 = (45)^2 + (135/4)^2 - 2(45)(135/4) cos 140 </span>
<span>c ≈ 74.1 mile
Hope this answers the question.</span>
