Find the distance x rounded to the nearest tenth.

anyanavicka [17]

Answer:

$x=0.1 ~ft$

Step-by-step explanation:

$cot30=\frac{B}{H} =\frac{B}{H}$

$\frac{\sqrt{3} }{2} =\frac{B}{H}=H=\frac{16}{\sqrt{3} }$

$sin70=\frac{X}{H} =\frac{P}{H}$

$sin70=\frac{x}{\frac{16}{\sqrt{3} } }$

$x=\frac{\sqrt{3} }{16 ~sin70}$

$=0.1152$

$x=0.1$
