Answer:
40,45,95
Step-by-step explanation:
The sum of the angles of a triangle are 180
2x+10 + 3x + 8x-25 = 180
Combine like terms
13x - 15 = 180
Add 15 to each side
13x - 15+15 =180 +15
13x = 195
Divide by 13
13x/13 = 195/13
x =15
The angles are
2x+10 = 2(15)+10 = 30+10 = 40
3x = 3(15) = 45
8x-25 = 8(15) -25 = 120-25 = 95
