Step-by-step explanation:

x +2x +2x -10 =180

5x -10 = 180

5x = 190

x = 38

Answer 2

Answer:

x+ 2x + (2x-10) = 180°

you know that ?

ok next

x+ 2x + 2x-10 = 180°

5x -10 = 180°

5x = 180°+10

5x = 190

x = 190/5

x = 38

x+ 2x + (2x-10) = 180°

therefore 38+76+66=180

therefore 180=180

I think 38 hope it will be helpful for you
