Given:

Given that a figure.

Required:

To find the


\begin{gathered} \angle1 \\ \angle2 \\ \angle3 \end{gathered}

Step-by-step explanation:

Now consider the first triangle in the given figure.

We know that the total angle sum in triangle is 180 degree.

Consider the unknown angle in triangle as x.

Consider the unknown anlge in t

Therefore,


\begin{gathered} 70\degree+55\degree+x=180\degree \\ 125\degree+x=180\degree \\ x=180\degree-125\degree \\ x=55\degree \end{gathered}

The angle of straight line is 180.

Therefore
