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

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

So,

Now, we will find the value of using the calculator, we get,

So, the missing value of 'x' to the nearest whole number is .
