Answer:
36.
Step-by-step explanation:
sec^2 (π/9) = 1 / cos^2 (π/9) = 1.13247
sec^2 (2π/9) = 1 / cos^2 (2π/9) = 1.70409
sec^2 (4π/9) = 1 / cos^2 (4π/9) = 33.1634
Adding these gives us 36 to the nearest whole number
If the longest side is greater than or equal to than the sum of the other 2 sides, then you won't have a triangle
(if one side is too long, then the other sides can't connect to reach each other)
67-35=32
35*3=105
Hope this helps!!!
