Question

So it’s the angle sun theory but i don’t understand it at all

Answer 1

`30\degree`

Step-by-step explanation

The angle sum theory states that:

This implies that:

`x+x+60+60=180`

Solve for x in the equation above:

`\begin{gathered} 2x+120=180 \\ \Rightarrow2x=180-120=60 \\ x=(60)/(2) \\ x=30\degree \end{gathered}`

That is the value of x.
