So since angle A is 120, so angles B+C=60 because there are 180 degrees in a triangle. So B:C is 2:1. So angle B is 40 and angle C is 20.

Answer:
y=\frac{3}{5}x\ +4.4
Step-by-step explanation:
Rise over run which would be 6/10 simplify that and you would get 3/5
Then you are looking for the intercept of y which would be 4.4.
Now, we're assuming this is for interior angles.
the sum of all the interior angles in a polygon is
180(n - 2) n = number of sides in a polygon.
now, this is an OCTAgon, it has OCTA=8 sides, so it has a sum of its interior angles at 180( 8 - 2) --> 180(6) ---> 1080°.
now, we already know seven of those eight angles add up to 1000, so... surely you'd know what the last one is.
