Answer:
80°

Explanation:
The sum of the angles in a triangle is equal to 180°. You can find another missing angle by using the given linear pair, meaning two angles are supplementary. 180-105 is equal to 75. If you add this with your other given angle (25), you get 100. To find the value of x, you subtract 100 from 180, getting 80°.
