Let x be the degree of angle a.
Angle b: 20+3x
Angle c: 55+x
We know that all angles add up to 180 degrees.
180=x+(20+3x)+(55+x)
180= 5x+75
180-75=5x
105/5=x
21=x
Angle a: 21 degrees
Angle b: 20+3(21) => 83 degrees
Angle c: 21+55 => 76 degrees
Hope I helped :)

Answer:
y=-1/3x+2/7
Step-by-step explanation:
y=-3x+6/7
x=-3y+6/7
-3y=x-6/7
y=-1/3x+(6/7)/3
y=-1/3x+(6/7)(1/3)
y=-1/3x+6/21
y=-1/3x+2/7
