Aas the 2 a’s are for the little lines that the top and the a is when you don’t have lines
1,656 would be the answer.
Okay, so you see that linear pair formed of angle 1,2,3
Now <1 = <5 and <3 = <6
So if 1 = 5, and 3 = 6
We also know that linear pair has 180 degrees and Hence proved angle 6,5 and 2 is equal to 180 degrees
