Question

Hi can you please help me answer this :)

Answer 1

Equation to find x:
`60+2x+x=180`

x= 40°

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
`m<1+m<2+m<3=180` so now we plug in what we know.

`60+2x+x=180`

Once we got our equation we can solve for x.

`60+2x+x=180\\60+3x=180\\3x=120\\x=40`
