From the given picture we can see
A right triangle DEC, where
The side opposite to angle C, ED has a length of 12 feet
The hypotenuse DC has length x feet
To find the value of x, we will use the sine ratio
[tex]\begin{gathered} \sin 70=\frac{opposite}{\text{hypotenuse}} \\ \sin 70=\frac{DE}{DC} \end{gathered}[/tex]
Since the opposite side DE = 12
Since the hypotenuse DC = x
