Sagot :

Explanation:

Angle b and the one that's 70º are vertical angles, so they are congruent.

Angles b and g are corresponding angles. They are congruent.

Angles g and e are vertical angles. They are congruent.

Angles a and b are supplementary - their measures add up 180º:

[tex]\begin{gathered} m\angle a+m\angle b=180º \\ m\angle a=180º-70º \\ m\angle a=110º \end{gathered}[/tex]

Angles a and d are corresponding angles. They are congruent.

Angles c and a are vertical angles. They are congruent.

Angles d and f are vertical angles. They are congruent.
