. Then, we look for the angle whose sine is
.
We have to, by definition:

So, we have to:

Answer:

Answer:
x = 20
Step-by-step explanation:
AE is an angle bisector, which means it cuts that triangle into 2 equal halves. So this means ∠BAE and ∠EAC should be equal to each other.
Set them equal to each other and solve for x.
∠BAE = ∠EAC
x + 30 = 3x - 10
40 = 2x
x = 20
