sin(53 degrees) = 0.8 (rounded)
sin(53 radians) = 0.4 (rounded)
sin(53 grads) = 0.7 (rounded)
The calculation gives 129.32 so the final 2 rounds down so that 129.3 is the answer.
53/10 is.
The two tens, nearest to 53, are 50 and 60. 53 is nearer to 50 (difference = 3) than it is to 60 (difference - 7). So 53, rounded to the nearest 10 is 50.
It is already rounded to the nearest integer.
50.
Zero.
It is 53.
53
You can type sin(53 degrees) into Google and get your answer that way. Also, I happen to know that 53 degrees is very close to one of the angles of a 3,4,5 right triangle, so sin(53 degrees) is very close to 4/5.
It is: 47 followed by 53
0
Sin(53 deg) = 0.7986, approx.
