For this question, we can use the same side interior angle theorem.
Angles 1 and 2 are same side interior angles, which means that they are the interior angles on the same side.
To find the angle measure of the angles, we can plug in the value we have.
[tex]A=6x+18[/tex]
[tex]A=6(10)+18[/tex]
[tex]A=60+18[/tex]
[tex]A=78[/tex]
[tex]B=9x+12[/tex]
[tex]B=9(10)+12[/tex]
[tex]B=90+12[/tex]
[tex]B=102[/tex]
To find if the oars are parallel, we can use the same side interior angle theorem, which states that if the same side interior angles are supplementary, the lines are parallel.
[tex]78+102=180[/tex]
Seeing as the angles are supplementary, the oars are parallel to each other.
Hope this helps.
頑張って!
