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

Nina [5.8K]
Okay so I don't know what you're trying to find out here, but if you're trying to find out how many words he has left after writing those two months, all you have to do is add. 35, 295 + 19, 240 and should get 54, 535. Then you subtract 95,234 - 54,535 and get 40,699.. So Zachary has 40,699 words left to write
