Ask the student a question, and give any hints about how they should answer this part.
A three-force body is an object acted upon by exactly three forces. When a three-force body is in equilibrium the lines of action of the three forces must either intersect at a common point or be parallel to each other. We can use this idea to find the reaction forces for three-force bodies.
In this problem the lines of action of force $\mathbf{B}$ and force $\mathbf{C}$ are known and their intersection point $X$ may be determined.
Use the given geometric information to determine distance $h$.
$h$ =
h = {h}
