Use tables to find the acute angle θ, given that: (iv) tan θ = .9347

Solution:-

In the table of natural tangent, look for a value (≤ .9347) which is sufficiently close to .9347.

We find the value .9325 occurs in the horizontal line beginning with 43^o and in the mean difference, we see .9347 – .9325 = .0022 in the column of 4’.

So we get, θ = 43^o + 4’ = 43^o 4’.
