Well you should know that a acute triangle should have all angles acute
OpenStudy (anonymous):
yes i think it is obtuse
OpenStudy (anaise):
I am just wanting to know that 3rd angle degree
I hate math.
You're correct.
OpenStudy (anonymous):
anyone else? i really wanna be right

jimthompson5910 (jim_thompson5910):
what's the measure of the missing angle?
hint: all three angles of ANY triangle add to 180 degrees
OpenStudy (anonymous):
yes I know that
OpenStudy (anonymous):
45 +35 = 80
180-80 = 100
jimthompson5910 (jim_thompson5910):
let x be the missing angle
(angle1)+(angle2)+(angle3) = 180 degrees
35 + 45 + x = 180
solve for x

x=100
OpenStudy (anaise):
That's what I was thinking, but it looks like it could be a 130 degree angle.
When we add it, we still get 180 degrees
as long as it's 130 degrees+
OMG X....
jimthompson5910 (jim_thompson5910):
yes x = 100
because 100 is larger than 90 degrees, we have an obtuse triangle
