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 [tex] \arctan (0.9) [/tex]
So, [tex] x^{\circ}=\arctan (0.9) [/tex]
Now, we will find the value of [tex] \arctan (0.9) [/tex]using the calculator, we get,
[tex] x^{\circ}=\arctan (0.9)=41.9^{\circ}=42^{\circ} [/tex]
So, the missing value of 'x' to the nearest whole number is [tex] 42^{\circ} [/tex].
