Answer:
The third exterior angle is 96° .
Step-by-step explanation:
Let us assume that the first angle be x.
Let us assume that the second angle be y.
Let us assume that the third angle be z .
As given
The sum of the measures of two exterior angles of a triangle is 264 degrees.
Thus
∠1 + ∠2 = 264 °
Now by using the property .
Sum of three exterior angles sum of a polygon is 360° .
Thus
∠1 + ∠2 + ∠3 = 360°
264° + ∠3 = 360°
∠3 = 360 ° - 264°
∠3 = 96°
Therefore the third exterior angle is 96° .
