6. jim_thompson5910 Group Title

hopefully that helps you see how to get x

7. Emily778 Group Title

what should I do next?

8. jim_thompson5910 Group Title

you would use the pythagorean theorem a^2 + b^2 = c^2 6^2 + 8^2 = x^2 solve for x

9. Emily778 Group Title

Uh.. the answers are a lot smaller than 10,000

10. jim_thompson5910 Group Title

how are you getting 10,000?

11. Emily778 Group Title

6^2+8^2=100^2=10,000

12. jim_thompson5910 Group Title

it should be 6^2 + 8^2 = 10^2

13. jim_thompson5910 Group Title

not 100^2

14. jim_thompson5910 Group Title

so somehow an extra zero popped up

15. Emily778 Group Title

there's 10 as an answer on here, but not 100.

16. jim_thompson5910 Group Title

$\large 6^2 + 8^2 = x^2$ $\large 36 + 64 = x^2$ $\large 100 = x^2$ $\large x^2 = 100$ $\large x = \sqrt{100}$ $\large x = 10$

Hint: the two triangles are congruent by the SSS property of congruence

19. Emily778 Group Title

:/

20. jim_thompson5910 Group Title

if two triangles are congruent, what can we say about their corresponding parts?

21. Emily778 Group Title

i dunno

22. jim_thompson5910 Group Title

let's say these two triangles are congruent |dw:1369697511047:dw|

23. jim_thompson5910 Group Title

and these two angles are corresponding angles |dw:1369697556004:dw|

24. jim_thompson5910 Group Title

since the two triangles are congruent, the corresponding angles are congruent |dw:1369697587635:dw|

25. Emily778 Group Title

okay, what next?

26. jim_thompson5910 Group Title

well what can you tell me about the angles 77 and x ?

27. Emily778 Group Title

THE SAME..! :D

28. jim_thompson5910 Group Title

yep, the two are corresponding angles so x = 77

29. Emily778 Group Title

oH. tHANKS. :0
