Answer:

x = 97.6

Step-by-step explanation:

cos = adjacent over hypotenuse

$cos(55)=\frac{56}{x}$

* multiply each side by x *

$cos(55)*x=xcos(55)\\\frac{56}{x} *x=56\\56=xcos(55)$

* divide each side by cos ( 55 ) *

$\frac{xcos(55)}{cos(55)} =x\\\frac{56}{cos(55)} =97.63302055$

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
