$(40, 9)$

Step 1

To find the $\tan (θ)$ between the x-axis and the line between the points $(0, 0)$ and $(40, 9)$ , draw the triangle between the three points $(0, 0)$ , $(40, 0)$ , and $(40, 9)$ .

Opposite : $9$

Adjacent : $40$

Step 2

$\tan (θ) = \frac{Opposite}{Adjacent}$ therefore $\tan (θ) = \frac{9}{40}$ .

$\frac{9}{40}$

Step 3

Approximate the result.

$\tan (θ) = \frac{9}{40} \approx 0.225$
