Round 2.48 to the nearest whole number. *

2

Step-by-step explanation:

So when it says whole number it means a number without a decimal, we would be looking at the two. Next you'd look at the number to the right of the two. If it it 5-9 you round up if it is 0-4 you keep it the same. In this case the 4 makes it stay the same.

(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: .64
