Answer:

      Equation to find x: [tex]60+2x+x=180[/tex]

      x= 40°

Step-by-step explanation:

We should know that if we add all the angles of a triangle it will give us 180 so the formula you could use is [tex]m<1+m<2+m<3=180[/tex] so now we plug in what we know.

[tex]60+2x+x=180[/tex]

Once we got our equation we can solve for x.

[tex]60+2x+x=180\\60+3x=180\\3x=120\\x=40[/tex]
