No I evaluate
sorry i forgot to add mg is 49N
Sin (64)=sin Alpha
cos (26)=cos alpha
cos (39) = cos beta
sin (51) = sin beta
sorry for the confusion.
I've re-done it.
I get 27.2587
Substitute the given values.
Evaluate the trigonometric functions.
Perform multiplication and division (from left to right) in the denominator.
Perform addition in the denominator.
I get the following:
Do you mean degrees or radians? Angles without the degree symbol are usually assumed to be radians
NOX Andrew has used radians where it appears you used degrees
yes sorry, i am using degrees.
Would you agree on the basis of using degree's that my answer of 27.258 is correct?

To 3dp as you did you'd still have to round that 27.258 to 27.259 because the next digit is a 7
