1. Bella buys dog food every four days and cat food every ten days. If she buys both kinds of pet food today, in how many days will she next buy both kinds of pet food?

(enter just the number - no words)

dog:4

cat:10

Step-by-step explanation:

4

Step-by-step explanation:

dog food will be 4 and cat 10

(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
