im soo confused

anonymous · Answer

it could be a isosceles triangle or a scalene, is there any thing about the measurements of the sides?

precal · Answer

Can't be isosceles traingle since 2 angles are not the same

phi · Answer

First, we see that all three angles add to 180.  So it is a real triangle, and not a trick question.  None of the angles equal each other.  That means none of the sides equal each other.  Does that ring any bells?

anonymous · Answer

i got it wrong

phi · Answer

acute scalene   describes this triangle

acute  means all 3 angles are less than 90
scalene  means all 3 sides are different lengths
