2) Use the law of sines to find the length of SR<br> sin⁡(A)/a=sin⁡(B)/b=sin⁡(C)/c

NeTakaya

Answer:

take 28 degree as reference angle

using sine angle

sin28=p/h

0.46=10/h

0.46h=10

h=10/0.46

h=21.73

therefore hypotenuse =21.73

again using sine rule

take 25 degree as reference angle

sin 25=p/h

0.42=SR/21.73

0.42*21.73=SR

9.12=SR

9.1=SR

Mya is buying juice boxes for her party. Which offer should Mya choose to get the lowest price per juice box? 1.) 2 juice boxes

NemiM [27]

For this case we must find the unit cost of juice box of each option and compare:

Option A: 2 juice boxes for $ 0.66

$\frac {0.66} {2} = 0.33 \frac {dollars} {box}$

Option B: 6 juice boxes for $ 1.92

$\frac {1.92} {6} = 0.32 \frac {dollars} {box}$

Option C: 9 juice boxes for $ 2.97

$\frac {2.97} {9} = 0.33 \frac {dollars} {box}$

Option D: 12 juice boxes for $ 4.20

$\frac {4.20} {12} = 0.35 \frac {dollars} {box}$

The most feasible option is B. That is, buy 6 boxes for $1.92
