Hillary made 48 chocolate chip cookies and y sugar cookies. how many total cookies did hillary make?

48+y= ?

the y is the variable and the ? could also be a variable  

she made 48 + y = a cookies.     not enough info is given to find the total.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer:

your answer is: c. 196 7/8 in^3.
