    Hello Punch:

    Let CT represents the height of a tree.

    1) $\displaystyle Tan(14)=\frac{CT}{AC}$ (Because it makes a triangle ACT)

    2) Let $\displaystyle S=\frac{CT}{2}$ (half of height).

    $\displaystyle Tan(SDC)=\frac{SC}{CD}$ (Triangle SDC)

    Find angle SDC i.e angle of elevation which is equal to angle of depression.

    Hope this helps!
