help plz

Hello,

To find the largest possible value of CF, we need to consider the relationship between altitudes and sides of a triangle. By using the formula CF = 2 * area(ABC) / AB, the largest possible value of CF occurs when AB is minimized. Therefore, CF will be maximum when AB is minimized to its smallest possible value.

H = 1/2 (1/CF + 5/36), 

   
1/1100=4 * sqrt[H * (H-1/12)*(H-1/18)*(H-1/CF)], solve for H, CF

H=0.0837303
CF ==35 - largest possible altitude
