damaskus [11]

Given:

There are given that the two paths and one path are 2 miles from the road.

Explanation:

Suppose the distance from the playground to the road is x.

To find the value x, we need to use the cos function;

So,

From the cos function in the given right angle triangle:

$cos50^{\circ}=\frac{x}{2}$

Then,

$\begin{gathered} cos50^{\operatorname{\circ}}=\frac{x}{2} \\ 0.64=\frac{x}{2} \end{gathered}$

Then,

$\begin{gathered} 0.64=\frac{x}{2} \\ x=0.64\times2 \\ x=1.28 \\ x=1.3mi \end{gathered}$

Final answer:

Hence, the correct option C.
