Step-by-step explanation:

x+10°+x+x+20°=180°

3x+30°=180°

3x=180°-30°

3x=150°

x=150°/3

x=50°

x+10°=(50+10)°=60°

x=50°

x+20°=(50+20)°=70°

Answer:

x + 10 + x + x + 20 = 180 \degree \\ 3x + 30 = 180 \degree \\ 3x = 180 - 30 \\ 3x = 150 \degree \\ x =  \frac{150}{3}  = 50 \degree \\ x + 10 = 50 + 10 = 60 \degree \\ x = 50 \degree \\ x + 20 = 50 + 20 = 70 \degree
