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)`.
