## brucebaner one year ago help me with triangles

1. brucebaner

2. Nnesha

|dw:1432763277608:dw| acute angle = all angle are less than 90 obtuse = an angle which is greater than 90 but less than 180 for obtuse one angle should be greater than 90

3. brucebaner

so its a Right triangle?

4. Nnesha

is there a box in the triangle ?

5. brucebaner

yes

6. Nnesha

remember all triangles add up to 180 degree

7. Nnesha

where i can't see

8. brucebaner

okay

9. brucebaner

i think its obtuse

10. Nnesha

and why do ou think that ?

11. brucebaner

because its more than 90 degrees

12. Nnesha

first find 3rd angle add both angles and subtract 180 from it

13. Nnesha

let's say x represent 3rd angle $\huge\rm 35+45+x =180$ solve for x let me know what yo uget

14. brucebaner

15. Nnesha

yes right

16. brucebaner

i got 80

17. Nnesha

did you subtract ?

18. brucebaner

not yet

19. Nnesha

okay subtract

20. Nnesha

how did you get 20 ? what did you subtract from 80?

21. brucebaner

22. brucebaner

i got 100

23. Nnesha

yes right |dw:1432763983110:dw| look at the definition i gave you tell me which triangle is it ?

24. brucebaner

obtuse?

25. Nnesha

why do you think ? :-)

26. Nnesha

gimme the reason why r u saying it's obtuse :-)

27. brucebaner

because its greater when 90?

28. Nnesha

bec one of angle is greater than 90 :-)

29. brucebaner

yes

30. Nnesha

if all 3 angles are less than 90 then actue if one of angle is greater than 90 just like in ur question then it's obtuse

31. Nnesha

if one angle is 90 then right triangle :-)

32. Nnesha

is there any 90 degree angle ?

33. brucebaner

no

34. Nnesha

so no it's not a right triangle

35. brucebaner

no

36. Nnesha

yes it's not a right triangle so which one is it ?read the definitions tell me with 100% confidence

37. brucebaner

acute

38. Nnesha

how is it acute ?

39. brucebaner

because they are all different angles?

40. Nnesha

i guess you din't read the definition that i gave you ?

41. brucebaner

can you give me the definition again?

42. Nnesha

43. brucebaner

so its obtuse?

44. Nnesha

yes it's

45. brucebaner

can you help me with one more?
