YZ = √ 5 and XZ = √ 2. Find XY. Answer in simplified radical form.

Question

in the given triangle picture Y vertex is 90 degree.
plz help.

Answer 1

sorry. If Y is the right angle of a right triangle, then the legs are XY and YZ
That makes XZ the hypotenuse, which must be the longest side of the triangle.

So what's the typo?

Answer 2

It’s a right triangle.
