Question

Use the image to answer the question.

A triangle has the vertices labeled upper E upper F upper D. The height upper E upper F is labeled 15, the base upper D upper F is labeled 20, and the hypotenuse upper D upper E is labeled 25. Angle upper E measures 60 degrees and angle upper D measures 30 degrees.

Does the Pythagorean Theorem apply to this triangle? How do you know?

(1 point)

No, because the angle at point F
is 90°
.

No, because the triangle is not a right triangle.

Yes, because you can use the Pythagorean Theorem on any triangle

Yes, because it is a right triangle.

Answer 1

Yes, because it is a right triangle.

Angle F is 90° (since E = 60° and D = 30°), and the side lengths 15, 20, 25 satisfy 15^2 + 20^2 = 25^2, so the Pythagorean Theorem applies.
