Answer:
1) x = 31
2) Both angles add up to be a supplementary angle (an angle who's sum is 180° altogether).
Step-by-step explanation:
1) Since both angles add up to be a supplementary, 
→ equation 1 + equation 2 = 180
→ (3x + 25) + (2x) = 180
Solving by applying algebra will give the answer "x = 31".
Hope this helps!
