He would maybe have 7.5 but I insist you the answer could be 8 too
107.75mThis is a trigonometric ratio problem. the angle of depression (10) is opposite the height (19m) and the distance is adjacent to the distance (x). opposite ad adjacent sides to the angle is a tangent problem.

plus in values, we know.

switch tan(10) and x using the products property.

plug in to calulator to get answer
x=107.75
