To form a triangle, the sum of the measures of the three angles must be equal to 180 degrees.
Let's check each combination:
1) 30 + 75 + 85 = 190 (not equal to 180)
2) 45 + 65 + 75 = 185 (not equal to 180)
3) 25 + 65 + 90 = 180 (equal to 180)
4) 40 + 55 + 95 = 190 (not equal to 180)
Hence, the only combination of angle measures that could form a triangle is 25, 65, and 90.
Identify the combination of angle measures that could for a triangle.
The options are
30,75 and 85
45,65 and 75
25,65 and 90
40,55 and 95
