Question 314975
<font face="Garamond" size="+2">


First off, you didn't specify, so I have to assume that your angle is measured in degrees.  32 radians would be a little silly anyway.


You can find an approximation of *[tex \Large \cos(32^\circ)] by using your calculator cosine function button.  Make sure you are in degree mode and apply the cosine function to 32.


If you know that *[tex \Large \cos(\varphi)\ =\ \frac{A}{H}], then you can always say that *[tex \Large A\ =\ H\cos(\varphi)].


Given that you have a hypotenuse of 30 and an angle of 32, you can say:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ A\ =\ 30\cos(32^\circ)]


A little calculator work and you will have your answer.
