This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Label the vertices of the triangle A, B, C, with A at the top, B at the bottom left, C at the bottom right. Let the lines be BE and CF, where E, F are on lines AC and BC respectively. Let O be the point of intersection. Draw AO, which splits x into 2 triangles, with area y and z.
Hint: Apply the fact that for two triangles with the same height, the ratio of their areas is equal to the ratio of their base.

But sir, how come we know about the heights. What can be its use then; help me out of this, please!
