Every morning Sam walks to the village dairy to buy fresh milk. The dairy is 1055 m from his house. How much distance in kilometer does Sam walk every morning if he walks both ways

2.11 km

Step-by-step explanation:

Walking both ways means that Sam walks a distance of:

= 1,055 + 1,055

= 2,110 meters

There are 1,000 meters in a kilometer so the number of kilometers walked is:

= 2,110 / 1,000

= 2.11 km

(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
