Answer:

Step-by-step explanation:

1. Remind that

$\tan \left(\dfrac{\pi }{4}\right)=1.$

Here you can use trigonometric table to find the value of $\tan\left(\dfrac{\pi}{4}\right)$ , or you can remind that $\dfrac{\pi}{4}=45^{\circ}$ and $\tan45^{\circ}=1$ because special right triangle 45°-45°-90° is isosceles (with congruent oppposite and adjacent legs) and the ratio between the opposite leg and adjacent leg is equal to 1.
