Respuesta :

The sum of the exterior angles is 360°
A 1 + B 1 + C 1 = 360° 
264° + C 1 = 360°
C 1 = 360° - 264°
C 1 = 96°
Answer:
The measure of the third exterior angle is 96°.

Answer:

96°


Step-by-step explanation:

The sum of the exterior angles of a polygon is always  360°.

Hence, the sum of the 3 exterior angles of a triangle is also 360°


Sum of 2 of these angles are given as 264°. So it follows that:

264° + third angle = 360°

third angle = 360° - 264° = 96°


So, measure of the third exterior angle is 96°.
