Show your work i have the question and my answers in picture i just want to make sure i'm correct question number i got x=16 and question number i got they are parallel

#3 you are correct.

#4 you are correct.

Step-by-step explanation:

#3) Similar triangles have common ratio for all 3 sides.

AD=24 DB=27 EB=18

DB/AB = EB/CB

DB CB = EB AB

DB (CE+EB) = EB (AD+DB)

27(CE+18)=18(24+27)

CE=18(24+27)/27 - 18 = 16

#4) If the triangles are similar then their third sides are parallel

AD=15 DB=12 so AB=27

AE=10 EC=8 so AC=18

AC/EC = 18/10 = 9/4

AB/DB = 27/12 = 9/4

The triangles are similar, so BC || DE

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 : )
