Answer:
x = .9
Step-by-step explanation:
Tan = Opposite over Adjacent
[tex]tan(83)=\frac{7}{x}[/tex]
* multiply each side by x *
[tex]tan(83)*x=xtan(83)\\\frac{7}{x} =7\\xtan(83)=7[/tex]
* divide each side by tan(83) *
[tex]\frac{xtan(83)}{tan(83)} =x\\\frac{7}{tan(83)} =0.8594919263\\x=0.8594919263[/tex]
* round to the nearest tenth of a foot *
we get that x = .9
