Answer:
The length of each side of the polyhedron, s is 4.142 or
= 
Step-by-step explanation:
If we take the distance of the length of the side of the cube where Donatello make the cut to the corner of the cube as x we get the side of length each polyhedron as

x·√2 because we have an hy
Therefore, the original cube had sides of length
10 = 2·x + x·√2
Solving for x we get

Therefore the length of s is x·√2 which gives

The length of each side of the polyhedron, s = 4.142.
Answer:
75
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle:
3x + 2 + 55 = 13x - 3 add like terms
3x + 57 = 13x - 3 export like terms to the same side
57 + 3 = 13x - 3x
60 = 10x divide both sides by 10
6 = x to find angle FAB replace x with 6
13*6 - 3 = 75
