22.island a is 160 miles from island b. a ship captain travels 170 miles from island a and then finds that he is off course and 200 miles from island b. what bearing should he turn to, so he is heading straight towards island b?

we know that

Applying the law of cosines: 

c² = a² + b² - 2abcos(C) 

where: 

a,b and c are sides of the triangle and C is the angle opposite side c 

let

a=170 mi

b=200 mi

c=160 mi

that is 

160² = 170² + 200² - 2(170)(200)cos(C) 

solve for C 

25,600 = 28,900 + 40,000 - 68,000cos(C) 

25,600 - 28,900 - 40,000 = -68,000cos(C) 

-43,300=-68,000cos (C)

cos (C)=0.6367

C=arc cos(0.6367)> C=50.45°

hence, 

he should turn in the direction of island b by

180 - 50.45 = 129.55 degrees

the answer is

129.55 degrees
