    go to the "angle x" corner of the triangle then stare at the triangle opposite side = ? |dw:1443509158791:dw|

    Yes, 8 is the opposite side. and the longest side, 17, is the hypotenuse.

    So we know "hypotenuse" and "opposite side". Now, which trig ratio involves those two ?

    You need to know trig ratios before attempting these problems

    Yes, \[\sin(x) = \dfrac{\text{opposite}}{\text{hypotenuse}} = \dfrac{8}{17}\]

    so \(x = \sin^{-1}(\frac{8}{17})\) use calculator

    Yes, it seems they want the answer in terms of degrees |dw:1443510003285:dw|
