What is 7.4689 rounded to the nearest tenth

7.5

Step-by-step explanation:

the tenths place is the first place in the decimals 0.1222 (the one)

If the number to the right of the tenths place is 5 or higher than the tenths place number moves up one. If it is 4 or lower than it stays the same.

The 6 is 5 or higher so the 4 rounds up to a 5

I hope that helps you :)

(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

1/2(2*4)=6 $$- agahajakanajak
