Answer 1

To determine which combination of angle measures could form a triangle, we need to use the triangle angle sum property, which states that the sum of the measures of the angles in a triangle must equal 180 degrees.

Let's check each option:

1. **45° + 65° + 75°**
- Sum = 45 + 65 + 75 = 185° (not a triangle)

2. **40° + 55° + 95°**
- Sum = 40 + 55 + 95 = 190° (not a triangle)

3. **25° + 65° + 90°**
- Sum = 25 + 65 + 90 = 180° (this is a triangle)

4. **30° + 75° + 85°**
- Sum = 30 + 75 + 85 = 190° (not a triangle)

The only combination of angle measures that could form a triangle is **25°, 65°, and 90°**.
