Answer:
x = 97.6
Step-by-step explanation:
cos = adjacent over hypotenuse
[tex]cos(55)=\frac{56}{x}[/tex]
* multiply each side by x *
[tex]cos(55)*x=xcos(55)\\\frac{56}{x} *x=56\\56=xcos(55)[/tex]
* divide each side by cos ( 55 ) *
[tex]\frac{xcos(55)}{cos(55)} =x\\\frac{56}{cos(55)} =97.63302055[/tex]
we're left with x = 97.63302055
Our last step is to round to the nearest tenth of a foot
We get that x = 97.6
