I have tried $(\mathrm{.}63$ x $73$ x sin$40)$ and it keeps telling me the answer is wrong. I don't know what I am doing wrong.

I you get any of the following answers, it will say its wrong too.

$29\mathrm{.}4973$

$29\mathrm{.}561$

$29\mathrm{.}56$

$29\mathrm{.}5665$

$29\mathrm{.}5577$

$35\mathrm{.}2437$
