Answer:

$\displaystyle 0,1922986515...\pi = \theta \\ 35° \approx \theta$

Step-by-step Step-by-step explanation:

$\displaystyle sec^(-1)\:1(177)/(823) = \theta; 0,1922986515...\pi\:[or\:34,613757274...°] \\ \\ \boxed{0,1922986515...\pi = \theta\:[35° \approx \theta]}$

$\displaystyle cos^(-1)\:(823)/(1000) = \theta; 0,1922986515...\pi\:[or\:34,613757274...°] \\ \\ \boxed{0,1922986515...\pi = \theta\:[35° \approx \theta]}$
