Question: In triangle XYZ, if angle X = 90 degrees, angle Y = 45 degrees, and side XY = 10 units, what is the length of side XZ?
Options:
Correct Answer: 10β2 units
Solution:
In a 45-45-90 triangle, the sides opposite the 45-degree angles are equal, and the hypotenuse is β2 times the length of each leg. Thus, XZ = XYβ2 = 10β2 units.
