Question

Can someone PLEASE help me with this?

Answer 1

x = 10

Explanation:

Since the ray AE is an angle bisector, it means that it cuts the angle 50 / 50, or perfectly in half.

This means that angle BAE and angle EAC are actually congruent

∠BAE = ∠EAC

`x + 30 = 3x - 10`

Get rid of x on one side. Since you are solving for x, use the more simple x

This becomes this ⇅

`30 = 2x + 10`

Subtract 10 from both sides

20 = 2x

20 divided by two

2x divided by two

x = 10
