Answer:

The third exterior angle is 96° .

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° .
