Answer:

50°

Step-by-step explanation:

if AE is angle bisector then angles BAE and EAC are equal

x + 30 = 3x - 10 add like terms

40 = 2x

20 = x

angle EAC is 3x - 10 so 3 × 20 - 10 = 50°

Answer:

70

Step-by-step explanation:

(x+30)-(3x-10)=180

x+30-3x+10=180

-2x+40=180

     -40  -40

-2x=140

1/2x=140

x=70
