Question What is the sum of the measures of the exterior angles of a triangle? If necessary, round to the nearest tenth. Answer Attempt 1 out of 2

To find the sum of the measures of the exterior angles of a triangle, we can follow these steps: 1. **Understanding Exterior Angles**: The exterior angle of a triangle is formed by one side of the triangle and the extension of an adjacent side. Each exterior angle is equal to the sum of the two opposite interior angles. 2. **Sum of Interior Angles**: The sum of the interior angles of a triangle is always \(180^\circ\). 3. **Calculating the Sum of Exterior Angles**: For any polygon, the sum of the exterior angles is always \(360^\circ\), regardless of the number of sides. This is true for triangles as well. Thus, the sum of the measures of the exterior angles of a triangle is: \[ 360^\circ \] Since the problem does not require rounding, the final answer is: **360.0**
