I have this problem I have tried to figure out.

So, Triangle have two angles which differs from each others by 45 degrees
opposite sides of those two angles are 5 and 2 what is the length of the longest side ?

Yep, It seems like right. Didn't notice we got answers for those problems.

5,4m is length of hypotenuse and angles are 21,5.. 66,5.. and 91,9..

Well, thanks for help though

No... sum of angles in a triangle = 180 degrees.

The triangle isn't right-angled, so "hypotenuse" isn't the correct term for the longest side. The answers are correct, but should be found to at least three significant figures.

Well, I didn't know you can't say hypotenuse if the triangle isn't right-angled Also, there were more than three significant figures - I just dropped them out.

Good to have forum like this. Know where to turn if math problems get too sticky.
