Question

Find the missing value to the nearest whole number of tan x° =0.9

Answer 1

90 is the correct answer

Answer 2

We have to find the missing value to the nearest whole number of tan x° =0.9.

Since, tan x° =0.9

To evaluate the missing value of 'x', we will take $\arctan (0.9)$

So, $x^{\circ}=\arctan (0.9)$

Now, we will find the value of $\arctan (0.9)$using the calculator, we get,

$x^{\circ}=\arctan (0.9)=41.9^{\circ}=42^{\circ}$

So, the missing value of 'x' to the nearest whole number is $42^{\circ}$.
