Find the tangent of each angle that is not the right angle. Drag and drop the numbers into the boxes to show the tangent of each

lapo4ka [179]

Answer:

$\tan \angle A$ = $1.33$

$\tan \angle B$ = $0.75$

Step-by-step explanation:

Given:

$\triangle ABC$ is a right triangle.

$\angle ACB = 90\°$

To find:

$\tan \angle A$

$\tan \angle B$

We know that tangent of an angle is given by the ratio= $\frac{Opposite\ side}{Adjacent\ side}$

The opposite side and adjacent side is taken with respect to the angle for which the tangent is to be found.

$\tan \angle A$ = $\frac{BC}{AC}=\frac{4}{3}=1.33$

$\tan \angle B$ = $\frac{AC}{BC}=\frac{3}{4}=0.75$
