Tan x=3/5 nearest tenth

dolphi86 [110]

Answer:

$x\approx31\°$

Step-by-step explanation:

Given expression:

$\tan x=\frac{3}{5}$

To solve for $x$ to nearest tenth.

Solution:

We have:

$\tan x=\frac{3}{5}$

In order to solve for $x$ we will tan inverse tan on both sides in order to isolate $x$ .

$\tan^{-1}(\tan x)=\tan^{-1}\frac{3}{5}$

$x=\tan^{-1}\frac{3}{5}$ [ Since $\tan^{-1}(\tan \theta)=\theta$ ]

$x=30.96\°$

We will round to nearest tenth. So,

$x\approx31\°$ (Answer)
