2. Find tan A for the right triangle below:

Andreyy89

Answer:

$tan A=\frac{8}{15}$

Step-by-step explanation:

According to the trigonometric ratios the tangent of an angle is the ratio of perpendicular to base, i.e.

$tan\theta=\frac{Perpendicular}{Base}$

In the provided triangle the perpendicular is 8 and base is 15.

Compute value of tan <em>A</em> as follows:

$tan\theta=\frac{Perpendicular}{Base}\\tanA=\frac{8}{15}\\$

Thus, the value of tan <em>A</em> is $\frac{8}{15}$ .
