PLEASE NO TROLLS I REALLY NEED HELP Use this diagram to answer questions 8 - 10. (Note: Line AB is parallel to line EC)
8. What is the value of x? *
9. What is the measure of ∠A? *
10. What is the measure of ∠D?

yeah guys no trolls

Step-by-step explanation:

answer is x<

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
