Atriangle has measurements of 18, 34, and 39 units. is it a right triangle?

yes
no
not enough information to tell

thats not a system of equations, that is a solution

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
