how to calculate the value of theta_k in terms of theta_i and theta_j

how to calculate the value of theta_k in terms of theta_i and theta_j in the following non- linear formula

log(Theta_k +sqrt(1+theta_k^2) ) - sqrt(1+theta_k^2)/theta_k = log(Theta_i +sqrt(1+theta_i^2) ) - sqrt(1+theta_i^2)/theta_i + log(Theta_j +sqrt(1+theta_j^2) ) - sqrt(1+theta_j^2)/theta_j

If you have symbolic toolbox, you can use something like this;

syms a b c real % define a b c as real symbolic variables
eq = a-b = c;   % define equation to be solved
solve(eq,b)     % solve for b

FYI, in your equation, you have Theta_k and theta_k, which Matlab will treat as two different variables.
