The measures of the angles of a triangle are 2x+10, 3x, and 8x-25 what is the triangle
umka2103 [35]

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
