Step-by-step explanation:

\angle  H = 115 \degree ... (vertical \:  \angle s) \\  \angle  H  +  65 \degree  \\ = 115 \degree +  65 \degree \\  = 180 \degree \\

Therefore by interior angle test,

line \: AB || \: line \: CD

Answer:

Yes

Step-by-step explanation:

For lines to be parallel alternate interior angles should be equal

Angle GHD=180-angle FHD

=180-115 = 65°

Therefore angle AGH = angle GHD

So lines are parallel

Luda [366]

Answer:

The midpoint of MN is <u>(7,1)</u>

Add the x coordinates 7+7=14 then you divide that by 2 giving you 7.

Then you add the y coordinates together 6+(-4)=2 then divide by 2 and that gives you 1. Therefore the answer is (7,1)
