    Answer:

    25

    Step-by-step explanation:

    1. Make an equation: 12-(-13).

    2. Solve the equation. Since there are 2 negative signs (one to the right of 12 and another to the left of 13) they can cancel each other out and they turn into an addition sign. Then, you get 12+13. You can easily solve that and you will get the answer of 25 degrees.
