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

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
