Can u prove that triangleEBD and triangleABC similar

3. pumpgirls

idk

4. sauravshakya

So, at first we need to prove that two triangles are similar

5. pumpgirls

ok

6. sauravshakya

Angle EBD = Angle ABC.............Can u tell me. why?

7. pumpgirls

they similar

8. sauravshakya

Look at Figure............ what do u see?

9. pumpgirls

all sides are equal

10. sauravshakya

Nope......... they are common angles

11. sauravshakya

Did u see?

12. pumpgirls

ok yes

13. sauravshakya

Also, angle BED = angle BAC............

14. pumpgirls

yea

15. sauravshakya

corresponding angles as AC parallel to ED ....right?

16. pumpgirls

right

17. sauravshakya

Thus, triangleEBD and triangleABC similar by A.A axiom

18. pumpgirls

yea so what would my answer

19. sauravshakya

Now, As triangleEBD and triangleABC similar,|dw:1345725490764:dw|

20. sauravshakya

|dw:1345725580952:dw|

21. sauravshakya

Does that help?

22. pumpgirls

yeah but which one would i chose

23. sauravshakya

|dw:1345725698605:dw|

24. sauravshakya

Solve and get te value of x

25. sauravshakya

can u?

26. sauravshakya

@pumpgirls can u?

27. pumpgirls

how do i solve forx

28. sauravshakya

|dw:1345725939615:dw|

29. sauravshakya

got it?

30. pumpgirls

31. sauravshakya

18.3

32. pumpgirls

but thats not one of answers

33. sauravshakya

|dw:1345726189097:dw|

34. pumpgirls

okay I gotcha :)
