Three points are chosen on the graph of the equation $x^3 + 39xy + y^3 - 2197 = 0$ such that the points form an equilateral triangle. The area of that equilateral triangle, in simplest radical form, can be expressed as $\frac{a\sqrt{b}}{c}$. Also, $a$ and $c$ are coprime. What is the value of $a + b + c$?

Three rational numbers are in geometric progression. If we add 8 to the second number, the progression becomes arithmetic. Now if we add 64 to the third number, the progression returns to be geometric. What are these numbers?

Three rational positive numbers (none of which are integers) are written on a board. Every minute, the numbers $x, y, z$ on the board are erased, and the numbers $x+\frac{1}{yz}, y+\frac{1}{zx}, z+\frac{1}{xy}$ are written instead. After 5 minutes, the numbers on the board are $a, b, c$. Calculate the sum of all possib...

Three rays $OC$, $OD$, and $OE$ were drawn inside the obtuse angle $\angle AOB$, with $OC \perp OA$. $OD$ is the bisector of the angle $\angle AOB$ and $OE$ is the bisector of the angle $\angle BOC$. Find the measure of the angle $\angle DOE$.

Three rays $\ell_1, \ell_2, \ell_3$ are drawn through a point $M$ lying outside the circle $S$ ($\ell_2$ lies between $\ell_1$ and $\ell_3$). $\ell_1$ intersects $S$ successively at points $A$ and $B$. The circles $\omega_1$ and $\omega_2$ with centers $O_1$ and $O_2$ lying on $\ell_2$ ($O_1$ lies between $O_2$ and $M$...
