  • Nnesha
is there a box in the triangle ?
brucebaner
  • brucebaner
yes
Nnesha
  • Nnesha
remember all triangles add up to 180 degree
Nnesha
  • Nnesha
where i can't see
brucebaner
  • brucebaner
okay
brucebaner
  • brucebaner
i think its obtuse
Nnesha
  • Nnesha
and why do ou think that ?
brucebaner
  • brucebaner
because its more than 90 degrees
Nnesha
  • Nnesha
first find 3rd angle add both angles and subtract 180 from it
Nnesha
  • Nnesha
let's say x represent 3rd angle \[\huge\rm 35+45+x =180\] solve for x let me know what yo uget
brucebaner
  • brucebaner
so add and subtract it
Nnesha
  • Nnesha
yes right
brucebaner
  • brucebaner
i got 80
Nnesha
  • Nnesha
did you subtract ?
brucebaner
  • brucebaner
not yet
Nnesha
  • Nnesha
okay subtract
Nnesha
  • Nnesha
how did you get 20 ? what did you subtract from 80?
brucebaner
  • brucebaner
my bad
brucebaner
  • brucebaner
i got 100
Nnesha
  • Nnesha
yes right |dw:1432763983110:dw| look at the definition i gave you tell me which triangle is it ?
brucebaner
  • brucebaner
obtuse?
Nnesha
  • Nnesha
why do you think ? :-)
Nnesha
  • Nnesha
gimme the reason why r u saying it's obtuse :-)
brucebaner
  • brucebaner
because its greater when 90?
Nnesha
  • Nnesha
bec one of angle is greater than 90 :-)
brucebaner
  • brucebaner
yes
Nnesha
  • 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
Nnesha
  • Nnesha
if one angle is 90 then right triangle :-)
Nnesha
  • Nnesha
is there any 90 degree angle ?
brucebaner
  • brucebaner
no
Nnesha
  • Nnesha
so no it's not a right triangle
brucebaner
  • brucebaner
no
Nnesha
  • Nnesha
yes it's not a right triangle so which one is it ?read the definitions tell me with 100% confidence
brucebaner
  • brucebaner
acute
Nnesha
  • Nnesha
how is it acute ?
brucebaner
  • brucebaner
because they are all different angles?
Nnesha
  • Nnesha
i guess you din't read the definition that i gave you ?
brucebaner
  • brucebaner
can you give me the definition again?
Nnesha
  • Nnesha
first comment read it
brucebaner
  • brucebaner
so its obtuse?
Nnesha
  • Nnesha
yes it's
brucebaner
  • brucebaner
