Wimming Pool On a certain hot summer's day, 528 people used the public swimming pool. The daily prices are $1.25 for children and $2.25 for adults. The ceipts for admission totaled $985.00. How many children and how many adults swam at the public pool that day?
mere were 159 children at the public pool.

Step-by-step explanation:

Let the number of children = c

The number of adults = a

Total people = 528

c + a = 528   (I)

Total price  = $ 985

1.25c + 2.25a = 985 (II)

Multiply equation (I) by (-1.25).

(I)*(-1.25)      -1.25c - 1.25a =  - 660

(II)                1.25c + 2.25a = 985  {add, c will be eliminated}

                                       a =  325

Number of adults = 325

Plugin the value of a in equation (I)

c + 325 = 528

         c = 528 - 325

         c = 203

Number of children = 203

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
