We have to determine if triangle PQR is similar to triangle XYZ or not.
To determine if the two triangles are similar, we use three postulates
AA, SSS, SAS.
AA means two angles must be equal in both triangles.
From picture we can see that only one angle is given so we can't be sure about other angles.
SSS means all sides are in same ratio but we have been given value of only one side. So that is also not applicable.
SAS means ratio of two sides from both traingles is equal and both triangles share a common angle but that is also not the given case.
Hence final answer is D. "Cannot be determined".
