Answer 4

when rounding to 4 decimal places, u will have to look at the 5 decimal place and if it is 5 or greater than u will have to make the 4 decimal place increase by one.
tan(21) = -1.52749 <<look at the fifth decimal place it is greater than 5 so u will have to increase the 4 by 1, now what will it be?
