10

Answer 1

The measure of the third interior angle of a triangle can be found by subtracting the sum of the other two angles from 180°.

Step-by-step explanation:

In a triangle, the sum of all three interior angles is always 180°. So, to find the measure of the third interior angle, we subtract the sum of the other two angles from 180°.

Let's denote the measure of the third interior angle as x.

Therefore, x = 180° - 44° - 57° = 79°.
