Answer:
x = 12
Explanation:
Angle 4 and angle 2 are congruent to each other. Angle 6 is also congruent to angle 2. If both these statements are true, angle 4 is congruent to angle 6.
This means (8x + 4) = (6x + 28)
Now, you simply solve for x:
8x + 4 = 6x + 28
- 4 - 4
8x = 6x + 24
-6x -6x
2x = 24
2x/2 = 24/2
x = 12
