Billy is hiking in Colorado. He walks eastward four miles, then turns 60 degrees northward and walks \(8\) miles and then he walks another \(4\) miles in the east direction. How far is he from his starting point?
+36915 Via Pythag theorem:
Distance from origin = sqrt ( (4 + 8 cos 60 + 4)2 + (8 sin 60)2 )
