What does this mean idk but thanks for the free answer
Answer:
15=a
Step-by-step explanation:
how I got this is because a triangle is equal to 180 so you have to add all of the things together then you get 12a=180 the reason why I got this is because if you add it so 6x+3a-1+3a+1 so you add common terms then you will equal to 12a then you divide it on both sides so then you equal to 15
One goes up and down and the other goes side to side
