Answer:
The measure of angle 8 is 54 degrees
Step-by-step explanation:
We know that angles 4 and 2 are linear pairs. Linear pairs add up to 180. Write an equation. (10x+6)+(5x-6). Now solve. 15x=180. x=12. With this, we can find the value of angle 8 by using angle 4's measure because 8 and 4 are congruent because they are corresponding angles. So, plug it in. 5(12)-6=60-6= 54. Therefore, angle 8 is 54 degrees
