Answer:
a and b are 100° and 20°
Step-by-step explanation:
When a-b=80°
l think of 80 as a multiple of 20.
Also a+b+c=180°
Now think of table of 20 like 20/40/60/80/100/120/140/160/180
Since a-b=80
a=b+80
ln the list from 20 to 180,
20+80 is 100
like b+80 is a
So two angles are
20° and 100° and third angle is 60 so that all three add up to 180.
Hence answer is a and b are 100° and 20° respectively.
