Hello !
- for a triangle to be constructible, the longest side must be less than the sum of the other two sides. -
already, the denominator must be the same everywhere to be able to calculate, therefore:
11/2 = (11 × 4) / (2 × 4) = 44/8
then you have to ask yourself if
44/8 is smaller than
57/8 + 75/8 .
57/8 + 75/8 = 132/8
44/8 ⟨ 132/8
Yes, the triangle is feasible.
I hope I helped you !!
Have a good evening !!!
