answer: 3.078 inches.

step-by-step explanation:

based on the information provided, the triangle is like the one shown in the image attached.

then, in order to find the lenght of bc, you need to apply the following identity:

$sin\alpha=\frac{opposite}{hypotenuse}$

in this case:

$\alpha=38\°\\opposite=bc\\hypotenuse=5$

now you can substitute values and solve for bc:

$sin(38\°)\frac{bc}{5}5*sin(38\°)=bcbc=3.078\ in$
