Pleas help me i dont know how to figure out the angles

angle b = 60°, angle c = 50°

Step-by-step explanation:

angle b: 120° - 80° = 60°

this is because a straight line is 180*, therefore given the angle 120° we can work out the other by subtracting it from 180°

angle c: 60° + 70° = 130°, 180° - 130° = 50°

this is because angles in a triangle add up to 180°, therefore given two angles we can subtract them from 180° to get the third

hope this helps! :)

idk but i found this "the graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.  

so, since the point (9,2) lies on the graph of y = f(x), the point (11,2) lies on the graph of y = f(x-2)."
