Please help solve A and B. Problem 5: A diver explores a shallow reef off the coast of Belize. She initially swims d1 = 85.8 m north, makes a turn to the east and continues for d2 =151.6 m, then follows a big grouper (a kind of fish) for d 3 = 77.1 m in the direction 0 = 33.7 north of east. Finally, she swims d4 = 160.8 m south.

Finally, she swims d4 = 160.8 m south. * 50% Part (a) What is the straight-line distance, in meters, between her initial and final positions? R= 153.7 m X Attempts Remain CA 50% Part (b) Suppose she wants to swim back to her initial position in a straight line. In what direction should she swim? Express your answer as an angle in degrees north of west
