33. (9th grade) Construct triangle $ABC$ given the altitude $h_{a}$, the median $\boldsymbol{m}_{a}$, and the radius $R$ of the circumscribed circle around the triangle.
33. From $h_{a}$ and $m_{a}$, we construct a right triangle $A D E$ ($h_{a}$ - leg, $m_{a}$ - hypotenuse). Point $E$ is the midpoint of the base of triangle $A B C$, so the center of the circle circumscribed around triangle $A B C$ lies on the perpendicular to $D E$, erected at point $E$, at a distance $R$ from vertex $A$. By determining the center, we draw the circumscribed circle, then, extending $D E$ in both directions until it intersects the circle, we obtain points $B$ and $C$. The problem is possible when $m_{a}>h_{a}$.
