Question

use your calculator to find the angle, to the nearest hundredth of a degree, whose tangent value is 1/3. 18.43°, 0.32°, 71.57°, 0.35°

Explanation:

Step1: Recall inverse - tangent formula

If $\tan\theta = \frac{1}{3}$, then $\theta=\arctan(\frac{1}{3})$.

Step2: Use calculator

Use a scientific calculator in degree - mode to find $\arctan(\frac{1}{3})$. Enter $\arctan(1\div3)$ and get the result. $\theta\approx18.43^{\circ}$.

Answer:

$18.43^{\circ}$
