Answer:

x = 2

Step-by-step explanation:

All the red lines tell you that each side must be equivalent because the angles are aka equilateral triangle.

So, 2x+4 = 8

2x = 8-4

2x = 4

2x/2 = 4/2

x = 2

This is an equilateral triangle because the angles inside are same so that the sides of the triangle are same too
2x-4=8
2x=12
x=6
