Answer:
x = 9
Step-by-step explanation:
What we have here is a bisected angle. What this means is that an angle is being cut in half to create multiple angles. In this case angle E has been bisected. Since that is the case, angles 1 and 2 are equivalent to each other. Now that we know this we can solve for x.
Equation:
x + 8 = 2x - 1
8 = x - 1
9 = x
