If Jane walks North for 3 miles, turns 45 degrees to the right, and then walks another 4 miles, how many miles will Jane be from her starting point? Give your answer as a decimal rounded to the nearest hundredth.
+36916 ....make sure you use cos 135 if using cos law for this problem !
+36916 (3 + 4 sin 45)^2 + (4 cos 45)^2 = d^2 d= 6.478 miles (6.48 miles rounded)
