Given that ABC is a positive integer and satisfies a + C = 10, C + B = 13, try to judge whether a, B and C can form a triangle

Given that ABC is a positive integer and satisfies a + C = 10, C + B = 13, try to judge whether a, B and C can form a triangle

Let C be X
Then solve the equations
This is what we learned in junior high school. I forgot about it
So the solution of the equation is not written
The solution is C = 3, a = 1, B = 2
Square of a + square of B = 1 + 4 = 5 ≠ square of C
So it can't form a right triangle
If it can help you, please accept my answer
You know, typing is not easy
