18 = 1a + 2b
That’s the equation for it
Well, the Pythagorean theorem is helpful.
Does 7^2+19^2=25^2?
no it desn't, so no it is not a right triangle
you got all right just check it and do the other one
The answer is b,a,c
the reason I know this is because the angle opposite to the largest side is the greatest angle, the angle across from the smallest side is the smallest angle
