this means that ? = $sin^{-1}(\frac{8}{9})$ or ? = arcsin( $\frac{8}{9}$ ), depending on what calculator you have

plugging in $sin^{-1}(\frac{8}{9})$ or arcsin( $\frac{8}{9}$ ) into calculator will get you

62.73° or 1.09 radians

use the corresponding answer depending on if the question asks for degrees or radians
