Question

What are the measures of the other angles formed by the intersection

Answer 1

Given the figure in the attached image.

`\begin{gathered} m\angle1=m\angle3 \\ m\angle2=50^(\circ) \end{gathered}`

Reason: vertically opposite angles are equal.

Also;

`50^(\circ)+m\angle1=180^(\circ)`

Reason: supplementary angles.

solving for angle 1;
