Answer 1

34.

The green angles are equals because they are formed by the same line and two lines parallel to each other

the opposite angles by their vertex are equal, so

The value of the red angle is 70 because

$180-110=70$

so, for the exercise

$\begin{gathered} m\angle1=110\~ \\ m\angle2=70\~ \end{gathered}$

35.

Using the same way we determine the angles

all these are 180 °, so

$m\angle1=m\angle2=180\~$

36.

The red angle is 123° because

$180-57=123$

then

$\begin{gathered} m\angle1=123 \\ m\angle2=57 \end{gathered}$
