1.8

Explanation:

Step1: Use cosine function

In a right - triangle, $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$. Here, $\theta = 73^{\circ}$, the hypotenuse is $6$, and the adjacent side is $x$. So, $\cos(73^{\circ})=\frac{x}{6}$.

Step2: Solve for $x$

Multiply both sides of the equation by $6$: $x = 6\times\cos(73^{\circ})$.
We know that $\cos(73^{\circ})\approx0.2924$. Then $x = 6\times0.2924$.
$x=1.7544$.

Answer:

$1.8$
