Final answer:

The student is incorrect because the sum of the angles in a triangle is always 180 degrees. If both x and y are 65, then the sum of all three angles would be 195 degrees, which is greater than 180 degrees.

Step-by-step explanation:

The student is incorrect because both x and y cannot be 65. In geometry, the sum of the angles in a triangle is always 180 degrees. If both x and y are 65, then the sum of all three angles would be 65 + 65 + 65 = 195 degrees, which is greater than 180 degrees. Therefore, the student's measurements are incorrect.
