corresponding sides of the 2 triangles are in the same ratio identify which angles are equal in order to determine corresponding sides

3. anonymous

5/9

5. anonymous

5/x

6. welshfella

Try again! < BAD = < ACD ( because they both make a right angle with < CAD)

7. welshfella

|dw:1438188721953:dw|

8. welshfella

right because 5 and x are corresponding sides

9. anonymous

okay.. so would you divide 5?

10. welshfella

now angle ABD and CAD are equal so their corresponding sides can be written as a fraction also

11. welshfella

no we need another 2 sides to form an equation one from small triangle ( which will be in numerator) and one from larger trianglw)

12. welshfella

side corresponding to angle ABD = x CAD = ?

13. anonymous

9

14. welshfella

right so we have 5 / x = x /9 solve for x

15. anonymous

cross multiply?

16. welshfella

yes

17. anonymous

81

18. anonymous

45

i'm sorry.. >.< i'm running on no sleep &so my brain is definetly not functioning right. i noticed it was wrong after i noticed

21. anonymous

honestly have no clue what i was trying to multiply. hahah thank you so much. c:

22. welshfella

yea - tiredness affects your brain alright...

23. welshfella

so you can identify the correct choice now?

24. anonymous

yes. c: thank you so much for baring with me.

25. welshfella

c?

26. welshfella

no x^2 = 45 x = sqrt45
