Question

n the image above, Angle is an angle of elevation from the dog to the child.

Answer 1

In general, the angles of elevation depression are given in the diagram below

Thus, in our case,

Therefore,

$\begin{gathered} Elevation+A=90\degree \\ and \\ B+A=90\degree \\ \Rightarrow Elevation=B \end{gathered}$

Hence, the angle of elevation from the dog to the child is equal to B in size. The answer is option B.
