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