I don't have the picture, so I need to know whether the side labeled √7 is a leg (one of the equal sides) or the hypotenuse. For a 45°-45°-90° isosceles right triangle the relation is:

hypotenuse = leg × √2.

So:

- If √7 is a leg, then x (the hypotenuse) = √7·√2 = √14 ≈ 3.7.
- If √7 is the hypotenuse, then x (a leg) = √7 / √2 = √(7/2) ≈ 1.9.

Tell me which side √7 labels and I’ll confirm.
