incorrect
this is the sum of the triangles interior and exterior angles
check answer remaining attempts: 1

Explanation:

Step1: Recall the property of exterior angles sum

The sum of the exterior angles of any polygon is \(360^{\circ}\). A triangle is a polygon with \(n = 3\) sides.

Step2: Apply the property to the triangle

Since a special right - triangle is a triangle (a polygon), the sum of its exterior angles follows the general rule for polygons.

Answer:

A. \(360\) degrees
