Question

How do you do this math isn’t my best subject need help pls

Answer 1

70

Explanation:

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

x+30-3x+10=180

-2x+40=180

-40 -40

-2x=140

1/2x=140

x=70

Answer 2

50°

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°
