To determine if the Pythagorean Theorem applies to a triangle, you need to assess whether it is a right triangle. The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
From the information you've provided about angles, the triangle has an angle of 90° at point F, indicating that it is indeed a right triangle.
Therefore, the correct response to your question is: Yes, because it is a right triangle.
