Question

Find the approximate unknown angle o using inverse trigonometric ratios (sin-1,cos-1, or tan-1)

Answer 1

`\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]}`

OR

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