I appreciate all the help everybody has given me.

But again I have another triangle construction, this one seem kinda of tricky.

Here goes the question:

(i)Construct triangle from $\displaystyle a, b+c, $ $\displaystyle alpha$ (where alpha is opposite to $\displaystyle a $.

(i) where is the the "right place" for $\displaystyle b+c $

thanks everyone
