Respuesta :

(2x + 3) + (x+1) + (3x-10) = 180
6x - 6 = 180
6x = 186
x= 31

Answer:

x = 31 degrees

Step-by-step explanation:

First things first, all angles of a triangle add up to 180 degrees.

From here, we can put it into an equation:

2x + 3 + x + 1 + 3x - 10 = 180

Simplify

6x - 6 = 180

    + 6    + 6

6x = 186

Divide

x = 31

Hope this helps :)
