    but they gave four options are we supposed to pick any one option and work angle of descent for that ? |dw:1433385070524:dw|

    Opposite side = 15042 Hypotenuse = 30924 which trig ratio involves Opposite and Hypotenuse ?

    Yes so use sin ratio : \[\large \sin(x) = \dfrac{15042}{30924}\]

    \[\large x = \sin^{-1}\left(\frac{15042}{30924}\right)\] use ur calculator
