5-49.

The fact is *x* is a prime number so the conclusion is *x* = 2, so *x* = 2 is a prime number.

What is another fact you can say that would still give *x* = 2 as a conclusion.

Put that in the blank oval.

*x* is even, or *x* is less than 3 are possible answers,

because these fact lead to the conclusion *x* = 2.

What conclusion can you make about the legs of the triangle?
