Question

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

Answer 1

`\displaystyle 34°`

Explanation:

`\displaystyle csc^(-1)\:1(4)/(5) = \theta; 33,748988596...° \\ \\ \boxed{34° \approx \theta}`

OR

`\displaystyle sin^(-1)\:(5)/(9) = \theta; 33,748988596...° \\ \\ \boxed{34° \approx \theta}`
