Force = 2.8 Newtons.

The attached image shows the arrangement.

Angle made by the water stream with the ground

$\theta = 30^\circ$

The horizontal component is given by:

$|F|\cos \theta\\=2.3\cos(30)\\\\=2.3 \times \dfrac{\sqrt3}{2}\\\\=1.99$

Thus, the horizontal component of force is 1.99 pounds.
