HI
you again??

anonymous · Answer

yes lol. @misty1212

anonymous · Answer

I would assume that there are no obtuse angles, and what you're talking about is a right angle triangle, composed of a right angle where 2 and 2 meet, and 45 degree angles where either one of the "2" lines meets the "3" line. However, a diagram would make this question easier to solve

what about this one? In a  ABC, if  B = 60° and the ratio of two sides is a : c = 2 : √3 + 1, then  A= 45° @br08 true or false??

anonymous · Answer

Sounds to me like an isosceles triangle, and an obtuse angle would be possible if it was the top angle.

for which one the first or second question? @PsychoTink

anonymous · Answer

The first question. Seems to me like it could easily be describing this: http://www.factmonster.com/images/obtuse.gif

@valerie709 sorry, I am not sure how to solve these, I don't recall learning this, or I may have just forgotten...

so wouldn't that be obtuse? @PsychoTink
